Manchester United goalkeeper David de Gea has left David Moyes with a lot to live up to after claiming that Sir Alex Ferguson is the "best coach of all time".

The 22-year-old, who was bought by Ferguson from Atletico Madrid in 2011, has claimed that it was a "privilege" to work under the 71-year-old, who ended his glittering 26-year reign at Old Trafford at the end of the season.

"I am very proud to have had the privilege of working with Ferguson, it was a real pleasure," De Gea told AS.

"He is the best coach of all time and it is something I will be able to tell my children and my grandchildren. The best advice that he gave me was to simply give my all."

De Gea is currently with the Spain Under-21 team in Israel for the U21 European Championships.
