Aaron Ramsey and Alex Oxlade-Chamberlain are set to be passed fit for Arsenal’s must-win clash against Dynamo Zagreb on Tuesday night, Football Insider sources understand.

The midfield duo will ease the Gunners’ injury crisis after the club suffered the shattering blow of losing Francis Coquelin for between three and six months.

An Arsenal source has told Football Insider that Ramsey and Oxlade-Chamberlain were expected to train on Monday and then be named by Arsene Wenger in his 18-man matchday squad to face Dynamo.

This comes after Wenger ruled the pair out of the Champions League showdown at Emirates Stadium in the wake of Saturday’s 2-1 Premier League defeat at West Brom.

“I can rotate a bit within the squad but Ramsey will be short and Chamberlain will be short — and they are the two closest,” said Wenger on Saturday, as he assessed casualty list that includes eight senior players. “It looks difficult to have players back in time for Tuesday.

“At the moment I do not have not much room to rest anybody — it is a difficult moment for us with injuries.”

Arsenal must beat Dynamo at Emirates Stadium to set up a final-day showdown against Olympiakos and have any chance of progressing to the Champions League knockout stages.

Shattering blow: Coquelin could be out for six months with knee ligament damage

Shattering blow: Coquelin could be out for six months with knee ligament damage

They will be without midfield anchorman Coquelin, who could miss the rest of the season with sprained knee ligaments.

As revealed by Football Insider on Sunday afternoon, the Frenchman has sprained the medial collateral ligament in his knee and the Gunners’ medical team fear he will be sidelined for between three and six months.

But the return of Ramsey and Oxlade-Chamberlain, who have missed six and four Arsenal matches respectively with hamstring injuries, is a boost for Wenger and the team.
