Manchester United boss David Moyes says he has no concern about Wayne Rooney's focus, despite what is said in Sir Alex Ferguson's new autobiography, reports BBC Sport.

In his autobiography it says that Rooney is said to have demanded a move away just the next day after Manchester United won the title back from rivals Manchester City.

It says that the England striker went to Ferguson's office "the day after we won the league and asked away", although the 71-year-old Scot decided to let successor David Moyes make the decision on Rooney's future.

"Wayne is completely focused on his football. He has been since the first day back in pre-season," responded Moyes baring in mind Rooney picked up an injury which kept him out every pre-season match.

"He's in good form - he's looking after himself and playing well."

When asked about Ferguson's comments he said: "Alex Ferguson can do what he wishes. He's his own man. Certainly everyone at Old Trafford would love to hear what he has to say - the supporters certainly would.

"He has great knowledge and I am sure a lot of people will enjoy reading it.

"I am sure I will [read it] when the time arises - I have not got much time in this job, that's for sure."

Rooney is just one high-profile name to be mentioned by Ferguson, with Roy Keane, David Beckham and Cristiano Ronaldo featuring in the book published on Tuesday.

The book is very controversial, with arguments with many former Manchester United legends explained which perhaps gives more detail than is needed to be known.
