Very good striker as near as I can tell. Big bloke who's still able to run at defenders. He's having an excellent season for Torino and might drag them all the way to European football. I've seen Gattuso (who apparently found him somewhere in the lower divisions a coulple years back) compare him to Shevchenko, and I suppose he would know.
He's at that age where he needs to play though. I don't think he'd get game time here with our current options. He's too good to have on the bench but he's not going to displace Alexis (unless he truly is on his way out) or even Giroud. My feeling is that he'll go to Napoli or a similar club and then in a year or two make a big move.
