Though, if you could get him for reasonnable price, it could be a good buy. I mean, even if we want to get away from our old style (ie a target man up front) and start to play like Barcelona with little players, it could be good to have a big man to change our formation or playing style when necessary. It's important to have a plan B. Like what Spain did at the world cup with Llorente. I remember when they were struggling with their traditional playing style, they did play him, that changed the physiognomy of the game... But for £20m it would be to expensive, and I don't know if he wants to be that kind of player (benched..)
