Arsenal star Jack Wilshere is facing three months on the sidelines due to the ankle injury sustained against Manchester United, Mirror reports.

The Gunners midfielder may require surgery on his ankle ligaments to fix the problem, but even if the Englishman doesn’t go under the knife then manager Arsene Wenger will be without Wilshere eight weeks.

The 22-year-old has just recovered from another problem but has not suffered a similar injury to French right-back Mathieu Debuchy, who was out since September.

This will come as a huge blow for Wilshere and his manager, as the England international has been in good form for both club and country.

Wenger said: "It does not look good. When you see the picture (of the tackle), it is very bad.

"I don't think it was a tackle with the desire to hurt, I think he [McNair] went for the ball. But it was a late tackle, a tackle which a young player can do. It was a bad foul.

"There is no bone damage, we knew that straight away after the game, but there is ligament damage. I hope it will not be surgery, just in a boot. But it will be a few weeks. But after that mentally he won't care too much.

"It is just the extension of how much it is, which we should know Tuesday or Wednesday (of next week).

"It is so sad, because he just came back. You see in the big games he has the personality. It is more about his game, it shows you he is not scared to play and is ready to want to get the ball always."

Arsenal will try to overcome their 2-1 loss to Man United when they face Borussia Dortmund in a Champions League clash on Wednesday.
