Manchester United captain Michael Carrick has led the tributes to iconic manager Sir Alex Ferguson, who is in intensive care after undergoing emergency surgery on Saturday.
The operation is said to have proceeded "very well" and in the aftermath a flood of tributes poured in for the 76-year-old.
Among those most touched by his illness are current and former United playing staff, particularly those who had worked under the former Dunfermline, Rangers and Falkirk striker.
