Roy Keane is set to return for Manchester United in their Champions League clash against Sturm Graz on Wednesday. The news comes as a boost to the side after Ryan Giggs' injury. Giggs had a scan on a hamstring injury and is expected to be out for at least 6 weeks. Keane, who pulled a hamstring while on international duty at the start of the month, should be fit for the trip to face the Austrians. Alex Ferguson said, 'If Roy comes through then we will have quite a bit of experience in centre midfield with Scholes and Keane, and hopefully David Beckham will also be back.'
