Wilshere suffered a setback in his recovery on Monday from the ankle injury that was initially expected to rule him out for a week but now appears likely to sideline him for a minimum of six. The 19-year-old's absence would be a big blow to England manager Fabio Capello, who is already without Steven Gerrard for the matches against Bulgaria on September 2 and Wales four days later. It is also more bad news for beleaguered Arsenal boss Wenger, who said on Tuesday night: "I don't know if we are back to square one or for how long he will be out. "He's in a boot again, so that means he will at least be out for two or three weeks."
