He's deceptively quick. Gets by on skills and movement rather than pace though.
Anyway, the main concern isn't that he can't play centreforward in England. He's a complete player who can do pretty much what he wants as long as he gets the ball at his feet. Playing with Cazorla and Wilshere will be good for him in this regard. I can see Wenger turning him into something similar to van Persie but it's going to take time. Starting to warm to the idea though. Maybe we can get 15 league goals out of him next season. Having a skillful player like him centrally could bring a lot out of Podolski and Walcott too. Main areas for concern are that he's a bit injury prone and doesn't like physical duels very much.
Another thing to consider is that the market price for strikers is insane at the moment. Either you spend £45 million on someone like Cavani or Falcao or you buy someone like Jovetic who has all the attributes and then you build the player yourself. Meanwhile you use the largest chunk of the transfer budget to improve the defence and midfield instead. Looking at our team at the moment I have to say that the latter strikes me as a better idea. We need two defenders and at least one midfielder this summer. A goalkeeper and a rightfooted wide man would be a big plus too.
