That's the problem: he was great in his Charlton days... for a team that wanted to survive. He's not got the push or the nouse to play for a team that want to challenge.
Many a time (admittedly, less towards the end of the season) he stood in the box and watched the play go around him. Not because he was biding his time, but because he didn't have a clue what to do. That's why he did well as a lone striker - he didn't have to play intelligently then. Now that he does though, he's got no chance.
I'll pay 12p for him, I think that's more than enough.
