From what I've seen - and obviously we can't see most of his games over here - he's a good goal scorer but doesn't offer much else. Bit like a Brockie in that regard. Those kinds of strikers seem to struggle to make it in the Premiership (even Carroll has a few more strings to his bow etc)
We've seen with the likes of Bent that teams are slowly moving away from 'specialist' players and are giving gametime to more well rounded ones.
