Santi Cazorla could miss the rest of the season after suffering a shattering injury setback.

Arsene Wenger has confirmed that the Spanish playmaker has suffered an Achilles problem just as he was on the verge of completing his recovery from a knee injury.

Arsenal had pencilled in Cazorla for a return this month but his comeback has been delayed and there is a growing possibility he will not kick a ball for the team again this season.

The loss of the key midfielder would be a huge blow for a team whose title challenge has been dented over the last month.

Speaking at his media briefing on Wednesday, Wenger explained: “Santi is not doing too well. He has some Achilles problems that hold him (back). His knee is doing well but his Achilles has inflamed a little bit and we have to put him off impact.

“It is a reaction to him coming back. We have to see now how he responds. He had always a little tendonitis on his Achilles and we have to see how he responds to that.”

Achilles injuries are notoriously difficult to recover from and Cazorla now faces a battle to play any part in Arsenal’s title run-in.

In other Arsenal injury news, Wenger has confirmed that Alex Oxlade-Chamberlain will be out until the end of April with a knee injury sustained in the defeat to Barcelona last week.
