Arsenal have been handed a welcome fitness boost with the news that Theo Walcott could return to action in a month following a dislocated shoulder. Walcott sustained the injury while on international duty, with the Gunners desperately missing his presence on the wing since, struggling to break teams down. "Walcott is the closest [to returning] because he has four weeks before he sees a specialist again and he should get the green light," manager Arsene Wenger told the club's official website. However, there was less encouraging news on captain Cesc Fabregas and long-term injury victim Tomas Rosicky, who are likely to be missing for another two months. "Rosicky is eight weeks. Fabregas, I believe, will be six to eight weeks before playing," said Wenger. "I can understand [Fabregas's] optimism and we hope, but with a medial knee ligament you have to respect the time."
