"I moved to Manchester United when I was a 17-year-old kid. Nemanja Vidic was five years older than me and Rio Ferdinand nearly nine years, and at the time, they were the best central defenders in the world. They never had a bad game."

"With VAR, the refereeing errors will be reduced, and therefore, we'll all be on equal terms. It will take a lot of the responsibility from the referees on vital decisions, like penalties and goals, and they will make far fewer mistakes."
