Manchester United players, both past and present, have sent their best wishes to Sir Alex Ferguson who is seriously ill in hospital. The former United coach has undergone surgery for a brain haemorrhage, which the club say has gone well. He remains in intensive care. Ferguson, a former Rangers striker, won three Scottish championships, four Scottish Cups and the 1983 European Cup Winners' Cup in charge of the Dons. It was a similar story at Old Trafford, where his United teams ended Liverpool's dominance of the domestic game, with the highlight of Ferguson's time in charge a 1999 treble of Premier League, Champions League and FA Cup titles all in the one season.
