PHOTOS: Oxlade's back! But here's why he may not be fit for Uruguay

Alex Oxlade Chamberlain

Arsenal and England star Alex Oxlade-Chamberlain returns to World Cup training. He vies for a first-team place with Manchester United and Liverpool players.

England may have lost their debut outing in the FIFA World Cup tournament in Brazil but at training this morning, Monday, they received a fitness boost as Arsenal attacker Alex Oxlade-Chamberlain reported for duty.

Oxlade, 20, has integrated himself well into the national team as he seemingly is developing strong off-field ties with the likes of Daniel Sturridge and Raheem Sterling.

While Wayne Rooney struggles to assert himself on the pitch and make a sufficient impact that would warrant further starts in the competition, Oxlade-Chamberlain may provide a timely solution as he has good pace, showed excellent form when granted starting opportunities at the Emirates Stadium in the latter half of the season and is capable of aiding his left back - something England vitally need as Leighton Baines was continually exposed against the Italians on Saturday.

England compete in the second game on Thursday, when they tackle Uruguay but, even though Oxlade-Chamberlain is training with the first-team after recovering from his medial knee ligament injury last month, he will unlikely start the Uruguay match as he was training with a knee support - suggesting that his rehabilitation is not yet 100% complete.

England's final group match is on Tuesday, June 24 against Costa Rica, however, they must return a positive result - preferably a victory on Thursday - in order to give themselves the best chance of progression.
