The football world has been paying tribute to legendary Manchester United manager Sir Alex Ferguson this evening after news emerged that he has undergone emergency surgery for a brain hemorrhage.

The 76-year-old was rushed to hospital today to undergo the procedure, which United have since revealed went well.

However, Ferguson - who won 13 Premier League titles and two Champions League crowns during his time in charge of United - remains in a serious condition and faces a "period of intensive care".

Here, Sports Mole rounds up the tributes and well wishes sent to the Scot.
