His position as club captain became untenable after he criticised the playing staff, also when Sir Alex pretty much took the mickey out of his managerial hopes. I happened to agree with the criticism he levelled at some players (well, the abridged version printed in the press) but it was inevitable that senior figures at the club wouldn't stand for it and his contract would not be extended.
A sad day indeed but his best playing days are some years behind him and I don't believe it will hamper the club in that sense, tho' his advice to the younger players will obviously be missed.
An absolute legend who will never be forgotten. Not unlike Cantona, his outstanding contribution to the club will remembered by the fans via the medium of song in almost every top level match for many years to come.
