Ferguson compared David De Gea and Petr Cech
"I went to see Cech when he was at Rennes," said Ferguson. "He was 19 years of age at the time and I said to myself, 'Yeah, he's too young', but Chelsea bought him not long afterwards for £7 million or something and he's never been out of the team.
"So youth, age, it doesn't matter when you have the ability of a goalkeeper like Cech or, we know, De Gea has. He's young, he's quick and he has fantastic presence and composure. His use of the ball is outstanding.
