"There are times when you doubt yourself as a player, and think: 'Am I good enough?' he said.

"The time Jose Mourinho left me out of the Manchester United team ... there are moments when you do doubt yourself. I believe I was good enough to get back in the team, but I never really got that opportunity.

"I came on for one minute in the Europa League final, I was about to come on against Southampton in the League Cup final, and in those moments it was embarrassing."

"It was getting to a point where I was embarrassed," Rooney said. "I thought: 'I can't keep doing this,' as hard as it was to leave Man United.

"In the Southampton game, Mourinho came to me and said: 'I want you to lift the trophy.' I was like: 'Well, I didn't even play in the game.'

"He was persistent with it, and I literally lifted it and moved it on. I just knew ... What was I doing? I needed to move on and go somewhere else."
