Sven-Goran Eriksson has revealed Sir Alex Ferguson had numerous fights during his time as England manager.
Many of Eriksson's top players during 2001 and 2006 played their domestic football at Ferguson's Manchester United.
And Eriksson says Ferguson wasn't always happy with his squad selections.
"With Alex, the amazing thing was it was seven o'clock in the morning or earlier, always, when he was angry. And never 'Hello Sven, how are you?' It was 'whuurssshhhh' [straight into yelling]," the 71-year-old told the Sunday Times.
"He said: 'I will kill you. You are finished.' But I represented England and you have to stand up.
"What's right is right and what's wrong is wrong and when you say 'Don't pick Rooney because I'm going to kill you'…I said, 'F*** off, what's going on with you?'.
"And he was screaming. Whenever he got like that…it has no meaning. That's why I was, 'Alex, I will pick Rooney. Now, have a nice holiday. Ciao, bye'."
