He was unplayable in the second half of the season at Blackburn - I'm sure that is what convinced Rafa to sign him.
On the whole however, he's one of those talented players that has never been able to find that extra level to reach the top. And he's a gobby mentalist on top of things, as said.
The only thing that surprises me about this is the price. The other week, he was valued, in the press, at around 6-9M, however since City have been reported to be interested, this has risen to 15M. Redknapp needs his head checking if he pays that much for Bellamy.
