Arsenal manager Arsene Wenger has revealed that midfielder Jack Wilshere is a doubt for this summer's European Championships.

The midfielder, who has missed the entire season due to a broken fibula, is still three-to-four weeks away from making his return to the first-team action which casts a dark cloud over his presence for England at Euro2016.

"Jack is doing quite well but has still not been outside yet," Wenger said ahead of Wednesday night's clash with Swansea City.

"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."
