Former Manchester United goalkeeper Edwin van der Sar says Frans Hoek will be a positive influence on the club's shot-stoppers.
New United manager Louis van Gaal will bring in his own staff - including goalkeeper coach Hoek.
Hoek will join United after the World Cup and Dutchman Van der Sar knows the 57 year-old well.
"He groomed me and helped me learn all the things I needed to know to be a successful footballer over a lot of years," he said.
"Like Louis van Gaal, he's really exact with his exercises - they both put a lot of thought into them. He was one of the first guys I know who connected the goalkeepers with defenders and midfielders in terms of exercises.
"It wasn't only about practicing goalkicks as a keeper - he would think about the different situations you might yourself be in during a game and try to find exercises and drills for us that he would combine with the outfield players."
