Keane Has `Lost The Plot`

Roy Keane has "lost the plot" and is making "some really silly decisions" according to the man who ghost-wrote his autobiography.
Eamonn Dunphy - formerly a very close friend of the Sunderland manager - has laid into Keane with both barrels on Radio Five Live.
Keane's side have lost six of their last seven games and are in the relegation zone despite him spending around £40m this summer.
He has repeatedly suggested that he could walk away from the club and has recently looked like a man who has lost his way.
"He is rambling about all sorts of things and it's really ridiculous," said Dunphy. "He is in serious danger of getting relegated but I think that Roy Keane is beginning to believe the Roy Keane mythology.
"He is pontificating on everything. He's lost the plot. I have the highest regard for him, he's a remarkable, intelligent, family man, but he's lost the plot big time.
"He hasn't had a settled side and I think he is in a fog at the moment. Everyone gets there at some point in your life, when things get too much for you. You don't know where the levers for control are and he's making some really silly decisions. He paid all that money for Anton Ferdinand and dropped him. Then there is Diouf on the bench and out of favour.
"It has been apparent to me for the last 18 months that Roy Keane isn't going to be a serious manager. Like a lot of great players he doesn't appear cut out for management. It's becoming increasingly apparent. I just don't think he has the qualities."
