Norwich City midfielder David Fox is grateful to his former Manchester United boss Sir Alex Ferguson for career assistance.

Fox was quick to praise former manager Ferguson, who let him join Blackpool on a free transfer in January 2006.

"I had six months left on my contract so I went in and spoke to him and said 'I think it is time I left'," the midfielder said. "He agreed, he looked after me and was brilliant.

"A few weeks later I got a letter through the post from him thanking me for my attitude at the club and wishing me all the best for my career.

"It is a letter I have still got and I am very proud that he took the time out to thank me for my efforts and wish me luck."
