I just know that they paid a lot of money for a player that is really limited in what he can do. He's not going to offer much on defense and really requires a lot of service to be productive, which lends itself to very little flexibility in system(s). He seems like a good fit for Tony Pulis - except for when Pulis is completely parking the bus and just wants to play with speedy forwards to steal a goal on a break.
I just don't know why they paid so much for a player when that amount can pay for a few more Zahas and Cabayes (theoretically).
