Sir Alex Ferguson has branded criticism of the Glazer family by Manchester United supporters as 'unfair'.The Glazers' £790million takeover was greeted with outright hostility by some sections of United's massive fanbase. Brothers Joel, Avram and Bryan needed to be smuggled out of Old Trafford under police supervision when they completed their buyout in 2005. Although the viciousness of the opposition to their involvement has reduced, family members can still be the subject of isolated attacks on their visits to Manchester and rebel club FC United, set up as a direct result of the Glazer takeover, continues to attract huge numbers for their position in the English football pyramid. Chief among the current complaints are rising ticket prices, a refusal to speak to the media on any meaningful basis since Joel Glazer conducted an interview with in-house station MUTV in the aftermath of the takeover and a failure to outline the true scale of the repayments on the mammoth debt that has been lodged against the Old Trafford club. The latter concern may be addressed later this month, when United are expected to smash the world record profit figure for a football club, which the Glazer family will no doubt use to back up their belief the Red Devils legacy is in safe hands. And Ferguson would not disagree, claiming the family have always been firmly supportive and pointing out the stability at United compared to the problems which have existed at other clubs recently, notably Liverpool. 'At a number of clubs there have been problems with friction between managers and owners but you can see how smoothly the United ship is running as far as that is concerned, despite early hostility over the Glazer family's ownership,' he said. 'Those protests were unfair because they weren't given a chance but the Glazers kept their cool and our owners have been nothing but supportive. 'Good teamwork starts at the top and I am happy to say, that is what we have at Old Trafford.'
