Charlton was one of the United directors who appointed Ferguson in 1987.

"He is such a fantastic manager. Everything he has done has been fantastic," said Charlton at the launch.

"He is a sensational person in every form and I am really delighted for him.

"I am a director but I hardly do anything because we are winning all the time and it is all down to Sir Alex Ferguson.

"He would get up in the middle of the night and travel 300 miles if he thought there was a school boy that he could sign.

"He loves the game and we at the club have had nothing to do really."
