He's proved he's not a top level striker. He flopped at Atalanta, and he's not scored for Bordeaux. According to Bellamy, he had a bad attitude and there's a reason he came to us and not a bigger club, something Fulham are finding our now about their "star signings". I've also heard stories about him being a figure of ridicule amongst the kids, which is why Mackay changed his tact about him being "one for the future". Good luck to him but we certainly haven't missed him. His "header" against Man City is still the worst/best thing I've ever seen for City.
Still, he's ahead of Zohore in the Denmark striker rankings, which says a lot more about Ken's form than it does about Cornelius.
