Well excuse me, but when you look at the bench of Anderlecht, there are Hassan (he doesnt always start), Leiva, and so on... The reason is, in midfield there is Biglia, Boussoufa, Hassan, Goor and he isnt a real defender.. So dont blame him for sitting on the bench, there isnt just room for him...
Bojinov was also benched a lot at Fiorentina I think (dont shoot me if I'm wrong..), and when he arrived here, he was awesome.
VDB also wants to play in a foreign league, so I think when he leaves Belgium, he will be relieved I think.
I say, Juve get him now, before a Spanish club gets him (he is quite hot there)
