I'm not sure you know, I like Van Bommel but at 33 I'm not sure he's got the legs to cover for Van der Vaart and Sneijder, De Jong's mobility would be more suited to that. I don't think the two defensive midfielders will be a major problem when you face better teams because you usually get more space to play and there's less creative responsibility on the likes of De Jong and Van Bommel. But it's difficult when you come up against sides who stick men behind the ball, someone with a bit more craft and vision would be more suited. I think Sneijder would be more suited, he's more of a midfield man than Van der Vaart, more comfortable dropping off and facing the play.
I'm guessing Van Marwijk is just looking for continuity and balance, he's obviously got a way of playing and he wants to build an understanding between the players. You'll be fine, I can see you improving (in terms of performance) when you come up against more adventurous sides.
Trying not to look biased here, but van Bommel has been Holland's man of the match for the last two matches. Has won virtually all of his personal duels, made no defensive mistakes, made some sublime passes and is the real leader on the pitch. I'm not the only one saying that, but it's the general opinion over here in Holland. I know he isn't the youngest, but believe me when I say he's one of these players who could easily go on for another three years. He lives football, doesn't drink or go out much. In short he's the ideal son in law, just ask van Marwijk for his opinion on that.
Ah well, another three points added. See you in the next round.
