As have, a ridiculous number of other completely hopeless players, and lots of utterly crap players have scored dozens of goals in international games for their country. Several managers have been dumb enough to play/buy Crouch, why would it surprise you an international manager is capable of the same mistake?
Crouch really is rubbish, for all his height, he fouls whoevers next to him at 80%+ of his headers, he's always leaning on whoever he's up against, pushing people down. He's 6 ft whatever, but has chicken legs and the complete inability to actually lift his frame himself which is why lots of other players beat him to headers all the time. Its also his lack of power which means he rarely if ever scores those unstoppable killer headers, or gets great knock on's. Cahill will run up put his head on the ball generate a tonne of power, Crouch walks up, jumps and the ball just hits him in the head and goes somewhere, usually a high looping slow easy to defend type "knock on".
He's rubbish, he's always been rubbish, rubbish strikers still score now and then, thats life.
As for saying VDV links up with him better than anyone else, really, 9 games into the season, VDV can't have played more than 4 of them, VDV, is that really a good measure, considering variation in teams and situation surround the games?
If Crouch was 5'11 he'd not be a professional footballer, he's been dragged along all these years as he was that "big kid" that a manager has just in case.
If Spurs want to be competitive in the top 6, let alone challenge for the title, you need someone in Berbatovs level, not Crouch's, Kevin Davies is more useful than Crouch at being a lone idiot upfront creating problems.
