"I went to see Petr [Cech] when he was at Rennes. He was 19 years of age at the time and I said to myself "he's too young." Chelsea bought him at the end of the season for £7m and he's never been out of the team. So youth, age, doesn't matter when you have the ability of a goalkeeper like Petr Cech, or as we know David De Gea has. He's young, he's quick, has fantastic presence and composure, his use of the ball is outstanding. So all these are plus points that don't go away. He's got these natural things."
