Arsène Wenger has confirmed that Alex Oxlade-Chamberlain will undergo a scan on Thursday, amid fears that the Arsenal midfielder faces a long-term absence because of knee ligament damage.

Oxlade-Chamberlain, whose participation for England at the European Championship finals in the summer could be in jeopardy, also hurt his ankle in a challenge with Javier Mascherano during the first half of the Champions League last-16 first-leg defeat against Barcelona on Tuesday night. The 22-year-old left the Emirates on crutches.

Wenger has already ruled out Oxlade-Chamberlain from Sunday’s Premier League visit to Manchester United but it is likely that he will be sidelined for rather longer.

Wenger, meanwhile, said that Gabriel will return to train with the first-team squad on Friday before the game at Old Trafford. “He is coming back into the squad tomorrow,” said the Frenchman. “So we will see how he responds to that, but the signs are positive. He might be available for Sunday.”
