If he's on it, a LOT of high speed running and pressing. If he's not, expect him to go through the motions and probably go down with something and come off at half time.
He'll get plenty of goals and assists over there with the way your lot play (and the pens you'll win), but he also loves to cut in and balloon it over the bar. I'd probably have traditional finishing as his weakest trait.
He's also prone to losing the plot and will no doubt cost you dear with a needless red at some point, probably in El Classico.
