Manchester United goalkeeper David De Gea is happy working with new keeper coach Frans Hoek.
Hoek was United legend Edwin van der Sar's first goalkeeping coach at Ajax.
"For me and the rest of the goalkeepers, it's a new system," said the 23-year-old, who joined United from Atletico Madrid in 2011.
"Training is new for us, but he knows everything about goalkeepers. He always stops the training and tells us what was good and what was bad and that's important for us.
"The most important thing I have learned under him is about positioning. If you are in a good position, you have more time for everything.
"To be a goalkeeper for Manchester United, you have to be focused all the time. You may only touch the ball one time in a game, but you have to be ready."
