Neymar (Brazil): One of the youngest players for the host team has a nice resume, including a stint with Real Madrid's youth team before signing his first professional contract at 17. Despite a mediocre debut this past season with powerhouse Barcelona, the 22-year-old has 31 goals in 48 appearances for Brazil and was controversially left off the 2010 World Cup team. Expect him to find the net, especially when you consider his wildly talented supporting cast. EVARISTO SA/AFP/Getty Images

Darijo Srna (Croatia): Srna, right, is Croatia's team captain and most-capped player. He plays professionally for Shakhtar Donetsk, whose stadium is an hour's drive from the Ukraine-Russia border. Chelsea and Bayern Munich have unsuccessfully courted the midfielder and right back, who has an eye for goal. But he said his heart led him to stay in Ukraine. Oh, and he has a leg tattoo of a deer (or "srna" in Croatian) playing soccer. stringer/AFP/Getty Images

Miguel Herrera (Mexico): OK, fine, he's an ex-player. But forget Oribe Peralta, Giovani dos Santos and Chicharito. No position for El Tri has been more in dispute than manager. Since Javier Aguirre was sacked after the 2010 World Cup, five managers have helmed Mexico. Herrera's first squad thrashed New Zealand 9-3 in a two-game playoff to qualify for the World Cup. But given Mexico's group, don't expect his next games to go so swimmingly. YURI CORTEZ/AFP/Getty Images

Samuel Eto'o (Cameroon): The first World Cup for Eto'o, left, was in 1998, but don't call him old. He'll make you look silly, as he did in May when he mocked his Chelsea coach, Jose Mourinho, with an The first World Cup for Eto'o, left, was in 1998, but don't call him old. He'll make you look silly, as he did in May when he mocked his Chelsea coach, Jose Mourinho, with an old-man goal celebration . If you ask Eto'o, he has two more World Cups in him. The 33-year-old will prove integral to the Indomitable Lions' campaign, having notched 56 goals in 117 caps (not to mention 300+ goals for clubs in Russia, Italy, Spain and England).

Diego Costa (Spain): Picking one player among the reigning world and European champions is tough. But Costa, left, promises to entertain -- and not solely because Spain and the host nation sparred over the Brazil-born striker's services. After receiving horse placenta treatment (uh-huh) on his injured hamstring, Costa started in the Champions League final only to aggravate the injury and come off after nine minutes.

Daley Blind (Netherlands): He's no goal machine, but Ajax's 2012-13 Player of the Year is a true box-to-box midfielder. With Kevin Strootman out due to injury, the 24-year-old understudy should see additional playing time for his country. He'll have extra motivation, too: His father, Danny Blind, who also played for Ajax, is a coach for the national team and has been tapped to take the team's reins following the 2016 European Championship.

Alexis Sanchez (Chile): If La Roja wants to escape from a group boasting both 2010 World Cup finalists, it'll need a strong showing from this 25-year-old forward, seen at right. Sanchez can score, finding the net eight times in 11 caps last year. He also knows how to set up his teammates, as he's racked up 34 assists to complement the 47 goals he's scored in club competition since Barcelona paid generously for his services in 2011.

Tim Cahill (Australia): Cahill, right, is the Socceroos' all-time leading scorer and their oldest player. In 2012, he left Everton after eight seasons in the English Premier League, saying he hoped a move to the New York Red Bulls would prolong his international career. The good news for Australia is he's become more of a goal scorer since joining New York. The bad news? He's netted only one for New York this season. Cameron Spencer/Getty Images

James Rodriguez (Colombia): He looks like a kid but brings a mature game for a 22-year-old. Lightning-quick with deft ball control and passing, he's earned lofty comparisons to Colombian demigod Carlos Valderrama. Days before his 19th birthday in 2010, Rodriguez joined Porto, where he played three seasons before Monaco paid €45 million for his transfer. He notched 10 goals and 12 assists for the French side this season. Manu Fernandez/AP

Theofanis Gekas (Greece): Greece doesn't have any major stars on the international stage. Nor does it have overtly dangerous goal scorers. So it'll be interesting to see how Gekas, a 34-year-old club journeyman, performs in a relatively weak group. With 24 international goals and a ton of experience -- including club stints in Turkey, Spain, Germany, England and Greece -- he has the wherewithal to make a difference.

Yaya Toure (Ivory Coast): He says he'd be considered the world's best player if he weren't African. That's arguable -- read the soccer blogs -- but he's a force. At 6-foot-3, he aptly plays defensive midfielder but has tremendous ball control and knows how to find the net (see his 20 goals for Manchester City this season). Let's hope his remarks He says he'd be considered the world's best player if he weren't African. That's arguable -- read the soccer blogs -- but he's a force. At 6-foot-3, he aptly plays defensive midfielder but has tremendous ball control and knows how to find the net (see his 20 goals for Manchester City this season). Let's hope his remarks on birthdays and race don't distract World Cup watchers from his considerable skills. Dean Mouhtaropoulos/Getty Images

Shinji Kagawa (Japan): The attacking midfielder's speed, vision and creativity would likely guarantee the 25-year-old a spot on any club in the world. But this year, an underachieving and in-transition Manchester United featured him in only 18 games. He went goalless and notched only three assists. He'll need to shake off the rust if Japan is to advance out of an up-for-grabs Group C. The Asahi Shimbun/Getty Images

Luis Suarez (Uruguay): Yes, he just had Yes, he just had knee surgery , and Coach Oscar Tabarez says he can't be sure his magical goal conjurer will play. If Suarez plays, he promises to be a strong storyline in a tightly contested group. If he doesn't play, ditto. Uruguay has other goal scorers in Edinson Cavani and Diego Forlan, but neither enjoyed the form that Suarez displayed this season in netting 31 goals as part of the high-octane Liverpool offense.

Joel Campbell (Costa Rica): Keep an eye on the 21-year-old. Costa Rica's opponents certainly will. Signed by Arsenal at age 18, he's spent the last three years on loan to French, Spanish and Greek clubs. USA fans will also remember him for his ridiculous dive during a World Cup qualifier last year. He'll be looking to redeem himself -- and his ho-hum club form of late -- with a memorable Cup, but he'll have his work cut out. Kevin C. Cox/Getty Images

Adam Lallana (England): For the casual fan, the 26-year-old might not be among England's big names. Three years ago, he was playing in England's third division, and he hasn't scored in five caps. But he tallied 10 goals and six assists for an overachieving Southampton squad this season. As club captain, he's also displayed the leadership to complement his strong finishing, passing and tackling. Stephen Pond/The FA/The FA via Getty Images

Mario Balotelli (Italy): The Azzurri is stacked with some of the world's most skilled players, including Gianluigi Buffon, Giorgio Chiellini and Andrea Pirlo, but with one off-the-wall antic Balotelli can become the story. With as many hairstyles as goal celebrations, the 23-year-old AC Milan forward loves to bring drama, but he has serious finishing skills. That will be important for an aging Italy squad known for hunkering down on defense. GABRIEL BOUYS/AFP/GettyImages

Xherdan Shaqiri (Switzerland): The Swiss don't have much offensive firepower (only one player has double-digit international goals), but that might change as this 22-year-old is earning comparisons to the world's top attackers. Why haven't you heard of him? Three reasons: Franck Ribery, Arjen Robben and Thomas Mueller. Some of the world's best players are attacking midfielders at Shaqiri's club, Bayern Munich. Good mentors for a budding star. Sigi Tischler/Keystone/AP

Christian Noboa (Ecuador): Noboa, right, plies his trade in Russia and is known for creativity, solid passing and vision. He's not a goal scorer, but Ecuador will rely on him to generate offense because, with little defense to speak of, it will need to outscore its opponents. If Antonio Valencia, Jefferson Montero and qualifying star Felipe Caicedo can get on the end of Noboa's passes, that's not at all far-fetched. Mike Stobe/Getty Images

Paul Pogba (France): Les Blues want to forget a 2010 World Cup in which Les Blues want to forget a 2010 World Cup in which numerous kerfuffles between the players and manager made them a laughingstock. Pogba could be key to washing away those memories and is doubtless a future star for France. He'll feature in one of the World Cup's most talented midfields, feeding a dangerous striker corps. If you think Pogba is too young to crack the lineup, ask his teammate, onetime Juventus mainstay Claudio Marchisio, what he thinks. FRANCK FIFE/AFP/Getty Images

Jerry Bengston (Honduras): His performance for the New England Revolution has been lackluster. Just months ago, he wasn't sure he'd make the World Cup squad. He got the nod, likely because when you put him in Honduras' blue and white, he delivers a goal every other game on average. He's especially lethal with his back to goal. Honduras is outmatched on paper, so Los Catrachos will need Bengston and Carlo Costly to find the net. Luis M. Alvarez/AP

Angel Di Maria (Argentina): The perennially talented Argentines are a favorite to advance thanks to a strong defense and a set of strikers that would make any nation drool. The speed and pinpoint passing of Di Maria, left, should make the Real Madrid playmaker the star of an aging midfield. And Argentina's strike force should benefit considerably from linking up with a man who posted 87 assists (coupled with 36 goals) in the last four years for his Spanish club.

Vedad Ibisevic (Bosnia and Herzegovina): An ex-NCAA freshman of the year with Saint Louis University, Ibisevic, left, served stints in the lower leagues of France and Germany before entering the Bundesliga. Since joining Stuttgart in 2012, he's bagged 33 goals, and he has 20 goals in 51 caps for the national team. Big at 6-foot-2 and 180 pounds, defenders will surely look to keep him and fellow goalhound Edin Dzeko away from goal. DANIEL MIHAILESCU/AFP/Getty Images

Steven Beitashour (Iran): If Iran is to make it out of the group stage for the first time -- in a likely scramble for Group E's second-place spot behind Argentina -- it will need a spirited performance from its California-born defender. A true dual threat, the Vancouver Whitecaps right back and 2012 MLS All-Star is efficient on the back line and can also streak forward. Since 2011, he has led all MLS defenders in assists. SAMUEL KUBANI/AFP/Getty Images

Ahmed Musa (Nigeria): At 21, Musa has blazing speed but a habit of flubbing goal opportunities. In 37 caps for Nigeria, he's found the net only five times. Expect the Super Eagles to counterattack, and with John Obi Mikel and Victor Moses in the midfield, you can also expect the passes to be on time. Whether Musa and fellow international underachiever Peter Odemwingie can make the most of them may dictate Nigeria's fate. ALEXANDER JOE/AFP/Getty Images

Miroslav Klose (Germany): With his nose for goal and a knack for nodding headers home, Klose will be on defenders' minds. His 36th birthday falling days before the Cup, the elder statesman has 14 World Cup goals, one shy of Ronaldo (no, not that Ronaldo -- Brazil's Ronaldo, the one who actually has scored proficiently in World Cups). After breaking Gerd Muller's German scoring record, Klose will look to add the World Cup scoring record to his list of accolades. Boris Streubel/Getty Images

Nani (Portugal): Yeah, yeah, we were supposed to pick Cristiano Ronaldo. But with a witch doctor Yeah, yeah, we were supposed to pick Cristiano Ronaldo. But with a witch doctor tampering with CR7's leg , Portugal could find itself needing some speed and creativity. Enter the Manchester United winger, whose international experience is second only to Ronaldo's. With Portugal's midfield being a relative weak spot, a lot will ride on Nani's performance. He'll need to improve on his club form of late if Portugal is to go deep. FRANCISCO LEONG/AFP/Getty Images

Mix Diskerud (USA): He says it's an honor to wear the No. 10 donned by Tab Ramos, Claudio Reyna and Landon Donovan. With the latter, Team America's top scorer, surprisingly omitted from the team, the USA will need goals. While the 23-year-old midfielder buried one in a recent Azerbaijan friendly, the burden can't fall wholly on him. Clever and quick, look for him to seek out the more goal-minded Clint Dempsey and Jozy Altidore. Jamie Sabau/Getty Images

Kevin-Prince Boateng (Ghana): The Black Stars have aging stars. It's unclear if Michael Essien and Asamoah Gyan can match their past performances, so much will be expected of KPB. An astute tackler with decent speed -- and a resume that includes knocking the U.S. team out of the 2010 World Cup -- the German-born midfielder must finish and tackle well. He'll also need to be careful, because he's no stranger to bookings. VI Images/Getty Images

Adnan Januzaj (Belgium): The Belgians are young, and none is younger than the Manchester United wunderkind, seen at right. With one cap to his name -- and surrounded by some of soccer's top stars -- the 19-year-old might not see the field much. But consider this: In his first start for Manchester United, at 18, he scored two goals in a come-from-behind win over Sunderland. Legend has it that at age 6, he once scored 17 goals in a youth game. And if he gets playing time, he certainly won't lack confidence. Newscom

Sofiane Feghouli (Algeria): This guy's fun to watch. A midfielder for Valencia, he's arguably Algeria's most talented player despite being only 24. While he's capable of the occasional goal, defenders will be more worried about his quickness, ball control and his ability to place a pass on a teammate's foot in stride. Algeria has an inexperienced set of strikers, so they should benefit from being on the end of Feghouli's top-drawer passing. JEFFROY/SIPA

Ki Sung-yueng (South Korea): He's a controversial young fellow. He's snarked at fans, insulted his manager and once celebrated an Asian Cup goal with an impersonation that He's a controversial young fellow. He's snarked at fans, insulted his manager and once celebrated an Asian Cup goal with an impersonation that had some Japanese crying racism . Most recently, he put the wrong hand on his chest during the national anthem. All that aside, he's a talented central midfielder who's made more than one defender look silly since joining the English Premier League in 2012. Chung Sung-Jun/Getty Images
