Resultwise it's acceptable, but their play is very incoherent. He started the season preaching attacking football from out the back and told the media he was so proud of their intentions after losing 9-0 to AZ. He's since become a bit more pragmatic and they've had a few good results, but he's only 3 points above 15th place.
The low point of the season was him subbing in his taller 2nd keeper after 80 minutes to see out a 2-1 lead in a cup game against amateurs and losing 2-3 with said keeper looking bad for both goals.
Before this he did some youth coaching which says nothing really.
I hope he will become a great trainer, because I absolutely loved him as a player, but signs so far point to a new Van Nistelrooy rather than a new Xabi Alonso.
