Sir Alex Ferguson confirmed Wayne Rooney had asked for a transfer from Manchester United after admitting the England star was not keen to play against Swansea.
Ferguson, taking charge of United for the final time at Old Trafford before retiring, dropped a bombshell by leaving Rooney out of the matchday squad.
And later he gave his reasons, telling Sky Sports: "I don't think Wayne was keen to play simply because he had asked for a transfer.
"He wants to think it through in his mind, which is a good idea."
Although Ferguson is standing down, to be replaced by Everton boss David Moyes, he insisted Rooney would not be allowed to leave the Barclays Premier League champions.
"We are not going to let him go but he is a little bit frustrated at being taken off once or twice in the last few weeks."
It will be down to Moyes, who sold Rooney to United in 2004, to sort the situation out, which does not promise to be easy.
Boos from Red Devils supporters when the 27-year-old stepped forward to collect his fifth championship-winning medal indicated the rank and file support are not too impressed with the conduct of a player who very publicly asked for a move in 2010.
However, former United defender Gary Neville, working as a television pundit but whom, later this month, will become Rooney's coach for England friendlies against Republic of Ireland and Brazil, said the striker needed to sort himself out.
"Wayne is an emotional lad and you can see in the last couple of months he hasn't quite been himself," said Neville.
"Wayne Rooney wears his heart on his sleeve. He fights every refereeing decision. But he has been a bit vacant on the pitch. You can see something is wrong.
"But there is nowhere to go from here. I have seen players join Real Madrid and other great clubs in Europe. But they always want to come back.
"If you play for this club for 20 years it is not a bed of roses. You struggle mentally at times. He will be going through a difficult moment.
"But in a couple of weeks he will be coming away with England. Then he needs to have the summer off and hopefully get his head back to being a Manchester United player."
Neville feels Rooney's family, and agent Paul Stretford, have a crucial role to play over the next few weeks.
"This is a good kid," said Neville.
"He needs to surround himself with his family and his players. The ones who have been here for a long time will bring him round.
"He is not someone who will make rash decisions but he needs people around him to give him good advice. He has an agent and friends. They need to be giving him the right advice.
"This is the only club he should be playing at."
