Blackburn fans have suggested that JDT didn't favour him at Blackburn last season because he didn't have the legs/wasn't mobile enough to play the pressing game with the intensity that they wanted. They weren't criticising his effort or work rate, just saying he wasn't a fit for the system.
They also said that when Mowbray played him as a false 9 that it was awful. The success would depend on the players around him though and our personnel may be better suited to accommodating him there (plus they generally have a huge downer on all things Mowbray). Based on Mowbray's comments when he signed, I think the club have definitely brought him in considering him to be a forward option though.
