Until now, Albert Stuivenberg was active as a (opposition) scout for Louis van Gaal during the World Cup.
Stuivenberg will start work in Manchester immediately. Until LVG arrives, he and Ryan Giggs will be in charge of United's training sessions
According to United's website, Stuivenberg will be 'assistant coach'. I can see him in a role similar to Meulensteen under Ferguson
It's also possible Stuivenberg will act as a bridge between the academy and the first team. Van Gaal puts a lot of emphasis on youth players
Van Gaal will keep up to date with every detail of the academy. He'll want to know everything there is to know about United's prospects
A lot of managers ignore youth teams and just wait until they're told about a player who could be good for the first team. Not Van Gaal.
During the 2001 WC Van Gaal took charge of Holland u20 while he was in function as national (first) team manager. Why? Just because
As @Chriswin4 points out: gone will be the days of scattergun approach regarding loans. Van Gaal will map out a plan for Zaha, Powell, etc.
