Jack Wilshere "annoyed" with injury setback

Arsenal midfielder Jack Wilshere has admitted his frustration at suffering another setback during his recovery from an ankle injury.

The 20-year-old, who has not featured for the Gunners this season, felt pain in his ankle while running in a training session today and has revealed that he is unaware of when he will return to action.

"It is true I have had a setback," Wilshere wrote on Twitter. "I can't tell you how long I have been set back because I don't know! I am very annoyed but will stay strong."

The England international was originally expected to make his long-awaited comeback in February.
