AC Milan midfielder Nigel de Jong has hailed the impact of Holland's World Cup coach Louis van Gaal.
Van Gaal will take charge of Manchester United after Brazil 2014.
And former Manchester City midfielder De Jong said: "He is just one of a kind, in his way of working and especially the tactical discipline he has for the team.
"You've seen his resumé. He is a fantastic coach and, over the years, he has built a lot of experience in these situations. That reflects also on the group because if he is calm, and if somebody from the group makes the right decisions, you can take it forward easily. He is one of the first I have experienced that does tactical changes in games like he does. For me, it is a new experience.
"Everybody who knows him knows he does a lot of tactical changes depending on the match and how it progresses, so he did that well."
