Wayne Rooney has revealed in his autobiography that the worst telling off he has seen a player get from Sir Alex Ferguson was after United’s 1-0 defeat to Celtic in the Champions League.

Louis Saha missed an easy chance, with him appearing to believe he was offside, before seeing his last minute penalty saved by Artur Boruc.

It spurs some of the lads on, but it crushes others. I’ve seen the manager shout and scream at people and when they’ve gone back on the pitch their heads have dropped. They’ve lost it. It’s the worst ‘hairdryer’ I’ve seen. He’s in Louis’ face, shouting and screaming. But Louis isn’t the only one getting an earful. The manager knows I’ve been negotiating a new deal with the club and he saves some for me, ‘Players wanting more money from the club and new deals – you don’t deserve anything after that performance!’
