Arsenal boss Arsene Wenger insists Jack Wilshere will be fit for England's Euro2012 campaign.

The Gunners face an injury crisis ahead of tonight's Euro clash with Olympiakos as TEN players are out - seven of them first-team regulars.

Wenger said: "Yes, Wilshere will be ready for Euro 2012.

"I don't have any worries about that.

"He will spend 12 weeks in a boot and after that it is rehab. Twelve weeks brings us to around Christmas. If all goes well, you would think he will be fit again to play in half the time you are in the boot - six weeks.

"Count 10 weeks to be closer to the truth, so it's 22 weeks to be capable to play football again."
