Some of the opinions about Wesley Sneijder in this thread are conflicting. Some good things have been said, as well as some bad things. IMO Sneijder is a good young player with a lot of talent and I would be glad to have him here at Juve.
Sneijder's preferred position is in the centre of midfield but he can play wide on the left or on the right if necessary. He's a good passer of the football with impressive technique. He is comfortable with the ball at his feet, he has a good cross, he can take set pieces and he hits one hell of a long shot. His movement is good and he possesses more creativity and vision than most of the midfielders on the Juve roster so as I already said, I'd be glad to have him.
Wesley may not to be as professional or disciplined as your Paolo Maldinis or our own Alessandro Del Piero, but he's young and will learn. Zlatan wasn't exactly an exemplary pro when he came here and he still isn't now but he has certainly improved under Capello in the Juventus system. Specific characteristics aren't tolerated at Juve, Zlatan has learnt that and I'm sure Wesley would too if he made the journey from Amsterdam to Turin like Ibra did.
