London - Arsenal midfielder Santi Cazorla is set to miss the rest of the season after suffering an Achilles problem, Gunners boss Arsene Wenger revealed on Tuesday.
Cazorla has been out since November with a knee injury, but Wenger says the Spain midfielder now has an issue with tendonitis which could rule him out for the remainder of the campaign.
It was initially hoped the 31-year-old would be back at some point in March but, ahead of Wednesday's game with Swansea, Wenger gave a fresh prognosis on Cazorla.
"Santi is not doing too well," he said. "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."
Asked if he is now set to return in April, Wenger replied: "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."
The Gunners have struggled without Cazorla and are in danger of blowing their Premier League title bid after Sunday's 3-2 defeat at Manchester United.
Meanwhile, Cazorla's fellow midfielder Jack Wilshere is still looking at a minimum of three weeks before making his own long-awaited return having not played this season due to a broken fibula.
He is now set to miss England's friendly double-header later this month after Wenger confirmed he has not started training with the squad.
"Jack is doing quite well but has still not been outside yet," he said.
"Running, I think, starts again this week. Three to four weeks (until he is back). I can understand you worry for the England team. I worry as well. I'm a supporter of England."
