Jack Wilshere's hopes of making England's Euro 2012 squad have suffered another setback.

The Arsenal midfielder had started light training in a bid to return for the Gunners' fixture with Chelsea at the end of the month.

However, the 20-year-old has had to shelve any plans of stepping up his comeback after suffering a knee injury.

Wilshere has not featured for Arsenal at all this season after injuring his ankle injury in a pre-season friendly.

The England international has also suffered a number of setbacks during the course of his recovery.
