As the Premier League heavyweights jet off to all corners of the globe to complete their pre-season tours, the primary objective is to get the first-team regulars fit and firing ahead of the new campaign.

But for the up-and-coming players in the squad, the game time on tour is the perfect opportunity to show off their talent and give the manager something to think about.

Here's our lowdown on the youngsters heading off with five of the elite clubs.

MANCHESTER UNITED

As well as new signings Bastian Schweinsteiger, Morgan Schneiderlin and Matteo Darmian, Louis van Gaal has named a number of players from the Old Trafford academy in the squad that will play four International Champions Cup matches in the United States, starting on Saturday morning against Club America.

The defenders Tyler Blackett, 21, and Paddy McNair, 20, were promoted into the United first team during an injury crisis at the beginning of last season and went on to make 11 and 18 appearances respectively in total.

Both were rewarded with a new long-term contract towards the end of the campaign though, with new arrivals expected in the central defensive position this summer, they will have to assert themselves again during the tour.

The other youngsters heading stateside include Sean Goss, who was a surprise inclusion but someone who has impressed at Under 21 level last season.

Goss is a 19-year-old central midfielder who has drawn comparisons with Michael Carrick for his crisp passing and solid defensive work. He will no doubt benefit from the arrival of Schweinsteiger as he hones his skills.

The Belgian-born Brazilian playmaker Andreas Pereira made a couple of first-team appearances for United last season, including his Premier League debut in the 3-0 win over Tottenham in March.

Capped eight times for the Brazil Under 20 squad, whom he represented at the U20 World Cup back in May, Pereira was a prominent member of United's title-winning U21 side last season.

Jesse Lingard, 22, who made his first-team debut against Swansea on the opening day of last season, returns to the Old Trafford fold following a loan spell at Championship side Derby.

He was a member of the England U21 side at this summer's European Championship and scored the winning goal against Sweden.

LIVERPOOL

Brendan Rodgers has named a number of academy players for the pre-season tour of the Far East and Australia, which began on Tuesday with a 4-0 rout of a Thai All-star XI in Bangkok.

Goalkeeper Ryan Fulton, 19, has been with the club since the U10 team and competed with Danny Ward and Lawrence Vigouroux for the gloves in the U21 team last season. He made seven appearances there and was also first choice in Liverpool's run to the last 16 of the UEFA Youth League.

England youth international Joe Gomez is one of the summer arrivals at Anfield. Liverpool paid £3.5m for the Charlton Athletic defender, who is very highly-rated, and the 18-year-old will get to know his new team-mates during their whistle-stop tour of the Far East.

Part of the England team that won the European Under 17 Championship last year, he went on to play 24 times for Charlton last season.

Hoping for game time perhaps alongside Gomez at centre half is Daniel Cleary. The Dublin-born defender, 19, was a regular fixture in Liverpool's U21 and Youth League teams last season and is known for his no-nonsense style.

Although Manchester-born, Joe Maguire has been at Liverpool since the age of nine. The left back, 19, who isn't afraid to get forward, also features regularly for the U21 team and is eagerly awaiting his first-team bow.

Pedro Chirivella is a Spanish holding midfield player who moved to the Anfield academy from Valencia in the summer of 2013. As with many Spanish players in his position, the 18-year-old is technically excellent and a fine passer.

As well as playing in five matches in the continental Youth League competition, Chirivella made his first appearances at U21 level in 2014-15.

Jordan Rossiter looks for a pass during Liverpool's 4-0 win over the Thailand All-Stars in their opening friendly

Jordan Rossiter, the midfielder that Robbie Fowler compared with Steven Gerrard, scored on his first-team debut against Middlesbrough in the Capital One Cup last season and is tipped for a bright future at the club.

The England U18 international was Liverpool's academy player of the year in 2013-14 and captained the side in the Youth League last season.

Portuguese midfielder Joao Teixeira returns to the Anfield fold following a successful season on loan at Brighton in the Championship, where he made 35 appearances and scored six times. Now 22, the Sporting Lisbon academy product needs to prove he is first-team material.

Ryan Kent is a flying winger capable of playing on either the left or the right side and is given a first-team chance after an impressive season of six goals and four assists in 14 U21 outings.

The 18-year-old was also impressive in the UEFA Youth League, where Liverpool took on the likes of Real Madrid.

The 18-year-old winger Sheyi Ojo is awaiting his first-team bow but did produce some encouraging performances while on loan at Wigan Athletic last season, though his efforts couldn't keep them in the Championship.

Quick, skilful and capable of beating his opponent, Ojo will be hoping to follow in the footsteps of the now-departed Raheem Sterling and the emerging Jordon Ibe.

Left-sided midfielder Harry Wilson, 18, had an impressive season at U21 and U19 level, scoring and creating plenty of goals.

His abilities brought him to the attention of Wales boss Chris Coleman and he was fast-tracked through the youth ranks to become the youngest player ever to make a senior appearance in 2013.

ARSENAL

Arsenal are also out in the Far East, in the Barclays Asia Trophy in Singapore before returning to more familiar territory to take on Lyon and then Wolfsburg in the Emirates Cup.

As might be expected, Arsene Wenger has sprinkled his squad with a few up-and-coming talents to play alongside the established names.

Striker Chuba Akpom is the best known and Wenger has the 19-year-old earmarked for a greater first-team role in the season ahead, with additions to the nine first team appearances under his belt inevitable.

Akpom has been a prolific goalscorer for Arsenal's youth teams and also for England, where he is capped up to U20 level. He spent the tail end of last season on loan at Nottingham Forest, playing seven times, and started the tour in style with a hat-trick against Singapore on Wednesday.

Talented playmaker Dan Crowley has made waves in Arsenal's youth sides and was quickly promoted to U21 level following his arrival from Aston Villa in 2013.

At just 17 though, Crowley is still eligible to play in the UEFA Youth League and he scored five times in seven games last season, including a hat-trick in a 4-3 defeat by Anderlecht.

Alex Iwobi, who is the nephew of Nigerian legend Jay-Jay Okocha, is capable of playing centrally or on either wing and possesses lightning pace and incisive passing.

The 19-year-old also has an enviable scoring record, with 10 in 19 games for the Arsenal U21s last season, and he'll be aiming to get on the scoresheet in Singapore too.

Pulling on an Arsenal shirt for the first time will be Jeff Reine-Adelaide, the France U17 playmaker who joined from Lens this summer alongside Yassin Fortune in a combined £3m deal.

Wenger says Reine-Adelaide is an exciting talent: 'He's an offensive player but he can develop into an all-round midfielder as well. At the moment, he plays on the left or the right but I think he can develop as a central midfielder as well.'

Another in that mould is 17-year-old Chris Willock, who has been playing for Arsenal's U18 team and also scored against Galatasaray in a 5-1 UEFA Youth League win back in October.

Last but certainly not least is Gedion Zelalem, the teenage midfielder who made his senior debut when he came on in Arsenal's FA Cup win over Coventry City in January 2014.

Although eligible to represent Germany having been born in Berlin, Zelalem was brought up mainly in the United States and has opted to play for them.

CHELSEA

The Premier League champions fly out to North America on Wednesday for the first part of their pre-season tour, which sees them play three times in the US.

Jose Mourinho has not formally named his touring party yet but among those included are Dominic Solanke and Ruben Loftus-Cheek.

Solanke, 17, capped a remarkably prolific 2014-15 when he scored the winner for the senior team against Thailand All-Stars in a post-season friendly back in May and should be in line for further first-team minutes next season.

The England U18 international was vital in Chelsea's UEFA Youth League success last season, ending the tournament with 12 goals in nine matches, and also helped them retain the FA Youth Cup.

Ruben Loftus-Cheek, seen here in action against Sydney in June, has been named in Chelsea's squad

Loftus-Cheek, 19, was also part of that Youth League triumph and made his senior debut back in December when he replaced Cesc Fabregas for the final seven minutes of the Champions League group game with Sporting Lisbon.

He was publicly criticised by Mourinho after Chelsea's 1-0 win over Sydney in a post-season friendly for not working hard enough for the team.

Also on the plane are Ola Aina, the 18-year-old right back who earned widespread praise after his accomplished performances in the UEFA Youth League and is already firmly established in the U21 side too as well as being capped by England up to U19 level.

Alongside him could well be centre back Jake Clarke-Salter, who has been on the books at Stamford Bridge since the under 9 age group and was rewarded with a first professional contract in December 2014 after playing at U19 and U21 level.

Goalkeeper Jamal Blackman has also been named in the touring party. The 21-year-old from Croydon, who is third-choice in the squad, signed a five-year contract in June 2014.

Other players who may have featured on Chelsea's tour, such as Izzy Brown, Lewis Baker and Andreas Christensen, have already gone out on loan.

MANCHESTER CITY

Manchester City are heading to Australia for a triple-header of matches followed by a stop-off in Vietnam on the return leg. Manuel Pellegrini is obviously keen to showcase the best of the City academy talent and has selected 14 kids to go along on the tour.

The Belgian centre half Jason Denayer, 20, who has just signed a five-year contract with City, enjoyed a successful season with Celtic in 2014-15, winning the Scottish Premiership, the League Cup and the PFA Scotland Young Player award.

Jose Pozo, the 19-year-old Spain youth striker who made his first-team breakthrough at City last season following injuries to Sergio Aguero and Stevan Jovetic, will be desperate for more minutes.

The Nigerian hotshot Kelechi Iheanacho, 18, was a key part of City's run to the FA Youth Cup final last season and will be seeking to emulate his success on last season's tour, when he scored in matches against Sporting Kansas City and Milan.

Enes Unal, an 18-year-old Turkey international striker, was City's first signing of the summer, arriving for £2m from Bursaspor and is tipped for big things.

The 20-year-old George Evans, who has been out on loan at Crewe Alexandra and Scunthorpe United, scored City's winner against Toronto in an end-of-season friendly back in May.

Centre back Ellis Plummer, a local lad who has been in City's academy since the age of 11, has been out on loan at Oldham Athletic and St Mirren in addition to his appearances in the Elite Development Squad.

Lifelong City fan George Glendon, 20, a defensive midfielder with plenty of experience at U21 level, could realise his dream of turning out for the first team during the tour.

The tall and powerful French midfielder Seko Fofana, 20, returns to the City squad following a season of 25 appearances at Championship side Fulham.

Spanish centre back Pablo Maffeo, 18, joined the club from Espanyol's academy in 2013 and has been playing for the EDS side in the under 21 Premier League and the UEFA Youth League.

6ft 5in Goalkeeper Angus Gunn, 19, is the son of former Norwich stopper Bryan Gunn and established himself as No 1 choice in the reserve team last season.

Bersant Celina, an 18-year-old midfielder who represents Kosovo, has also been a frequent performer in Patrick Vieira's EDS team and went with the first team to City's mid-season training camp in Abu Dhabi back in January.

Fleet-footed winger Brandon Barker, 18, was a big part of City's run to the FA Youth Cup final last season and also played in the U21s and the Youth League. He also has a good scoring record for England at U19 standard.

Spanish youth international midfielder Manuel Garcia joined City from Sporting Gijon in 2013 and having been on the EDS pre-season tour of Croatia last summer, he's now been promoted to the seniors.
