Well I'm Belgian but I have never seen a full game from the Belgian First Division. Crap it is.
The pieces I do watch are usually the highlights of the Liège match. My cousin is a fan and they play good football at times... so I saw some things from Witsel and like I said in the other threads about him: he's a good player, good technique, good passing, always very comfortable on the ball and he can play anywhere in midfield.
Still I would never rate him at £18 million
But like I said before and like has been said in this thread, Standard are trying to get as much as they can, certainly after Everton payed that much for Fellaini.
With selling Fellaini and in the next year maybe Witsel and Defour, they can be the richest club in Belgium. Can't blame them for asking such a price, there's always someone willing to pay it, like has been demonstrated by Everton.
About good prospects from Belgium, well we aren't known for our world class youngsters but anything can happen. We have a good batch of young players the moment, Witsel, Fellaini, Defour but also Van den Borre, Dembele and Kompany. It's a good generation of players but I had never thought they would end up in England for that amount of money. They are breaking into the national team last year and this year after the terrible results in the run-up to euro 2008. We ditched the oldies and just started using the young players after they showed their skill in the Olympics and the -21 championships.
