By now, many players have broken away from the pack. Several players, such as Blas Perez, have seen their prices rise significantly due to their consistent, week-in, week-out production. However, a problem arises this round due to international friendlies, affecting almost all fantasy teams. Jozy Altidore, Robbie Keane, and the aforementioned Perez have all been called up by their country’s respective national teams earlier this week and will not be available for this MLS Fantasy round. Coping during weeks such as these is incredibly hard, and how you deal with them could ultimately make or break your teams down the stretch. Without further ado, here are the player rankings for round four:

Goalkeepers:

Tyler Deric ($4.9, Hou) David Ousted ($5.5, Van) Jeff Attinella ($5.0, RSL) Steve Clark ($5.6, Clb) Chris Seitz ($5.1, Dal) Bobby Shuttleworth ($5.4, NE) Adam Kwarasey ($5.5, Por) Bill Hamid ($6.1, DC) Evan Bush ($5.1, Mtl) Luis Robles ($5.5, NYR)

Differential Pick: Jeff Attinella (0.3% owned, vs Tor). With Nick Rimando on international duty with the United States National Team, Attinella will be in goal for Real Salt Lake this Sunday. Going up against a Toronto FC traveling two time zones away and without Jozy Altidore, Attinella has a realistic chance towards a shut out for your fantasy team. The RSL defense has looked relatively solid in their first two games (with the exception of three very fluky goals against Philadelphia), and with an above-average goalkeeper in Attinella playing, they should fair pretty well against their Canadian counterparts.

Buyer Beware: Stefan Frei (8.5% owned, @ Dal). Although he is up against a Blas Perez-less FC Dallas, he is still facing a dynamic offense with Fabian Castillo, Mauro Diaz, and Tesho Akindele. Even without their top striker, it is inconceivable that Dallas will not score on Seattle. It is certainly not out of the realm of possibility that the shaky Seattle defense will find themselves picking the ball out of there own net one, maybe two times on Saturday.

Defenders:

Jamison Olave ($8.2, RSL) Kendall Waston ($8.6, Van) David Horst ($8.1, Hou) Matt Hedges ($9.1, Dal) Chris Schuler ($8.6, RSL) Hernan Grana ($6.6, Clb) Zach Loyd ($7.7, Dal) Andrew Farrell ($7.9, NE) Steven Beitashour ($7.7, Van) Liam Ridgewell ($8.5, Por)

Differential Pick: Jose Goncalves (0.6% owned, vs SJ). Back from his suspension, Goncalves is significantly cheaper since he last played. New England looked very solid in their shut out against Montreal last week, and could find another clean sheet against a San Jose team that had a cross-country flight midweek. On top of that, Goncalves has historically been known as a bonus point king, as usually reliable for two to three defensive points a week.

Buyer Beware: Ike Opara (11.9% owned, @ NYC). Up against a strong NYCFC side on a narrow Yankee Stadium field, Opara has a tough task ahead of him. Although the defensive bonuses may bail him out, there is a real chance that SKC defenders may lose a point because of conceiding 2+ goals in their game. David Villa can cause Sporting some serious problems, and has one of the greatest chances to score a goal this round.

Midfielders:

Javier Morales ($10.7, RSL) Pedro Morales ($11.1, Van) Fabian Castillo ($9.8, Dal) Ignacio Piatti ($9.5, Mtl) Harrison Shipp ($7.6, Chi) Lee Nguyen ($11.0, NE) Ethan Finlay ($8.1, Clb) Mauro Diaz ($9.0, Dal) Loyd Sam ($8.7, NYR) Kaka ($11.1, Orl)

Differential Pick: Sacha Kljestan (1.3% owned, @ Clb). The midfield trio of Kljestan, Felipe, and Dax McCarty has slowly grown into a strong partnership up the spine of the New York Red Bulls’ starting lineup. Although he has yet to put up fantasy numbers in the two games he has played, Kljestan runs the offense for New York, who played exceptionally well last week against DC. The Red Bulls have had a strong history against Columbus, and it would not be a shock if Kljestan put up a goal and/or an assist this weekend.

Buyer Beware: Sebastian Giovinco (5.4% owned, @ RSL). Toronto FC have to travel to Utah for a tough matchup against Real Salt Lake’s strong defense. Giovinco failed to produce against Columbus in Toronto’s last match, and without Jozy Altidore this week, one has to question whether or not Giovinco will put up the numbers he did in week 1.

Forwards:

Octavio Rivero ($8.7, Van) David Villa ($10.2, NYC) Federico Higuaín ($10.4, Clb) Juan Agudelo ($8.4, NE) Tesho Akindele ($8.1, Dal) Fernando Aristiguieta ($7.6, Phi) Chris Wondolowski ($10.7, SJ) Bradley Wright-Phillips ($10.7, NYR) Kei Kamara ($8.0, Clb) Obafemi Martins ($11.2, Sea)

Differential Pick: Devon Sandoval (3.7% owned, vs Tor). Real Salt Lake are missing their big striker, Alvaro Saborio, for this week, so Sandoval will be stepping into his role. Devon is a solid MLS forward and proven goal-scorer who has an a favorable matchup against a leaky Toronto FC defense, who are also missing right back Justin Morrow due to a red card suspension. It’s certainty believable that he will be scoring for the Claret and Cobalt in what should be a one-sided affair.

Buyer Beware: Dom Dwyer (7.6% owned, @ NYC). Following a 2014 campaign in which he scored 22 goals, Dwyer has yet to find his scoring boots for Sporting Kansas City so far in 2015. He has found himself in promising positions, but hasn’t been able to finish his chances. Up against a NYCFC defense that has only allowed one goal in their first three games, it doesn’t look promising for Dwyer this week.
