Ricardo Carvalho has revealed how he challenged former Chelsea boss Jose Mourinho to sell him after a falling out.

Carvalho admits he clashed with Mourinho when they first came together at Chelsea over the way he would train when they were together at Porto.

He told the Sunday Times: "I improved a lot when I arrived in England but you know Jose had that idea from Porto. 'Ah, you are sleeping.' Even a small mistake. 'During the game you never do that.' I had a meeting with him after the first year. I said to him, 'Here the football is physical and I can't enjoy, so for me I would prefer to go.' He took it a little bit too serious and the reaction was, 'Okay, if you want to, go.' But I knew he'd said to the club, 'No, I don't want to let him go.'

"Because I didn't like that, I reacted and said I was disappointed with him. He said one thing to me and for the others he said no chance. I didn't play for two or three weeks, but then he called a meeting to sort things out and said, 'I apologise. You spoke, you shouldn't have spoken, but I reacted worse than I should. But now if you deserve to play you will.'

"Two weeks later I started to play and I started to enjoy the games more here. I got better so he was happier with me."
