Been doing a bit of scouring around the Burnley forums and it appears that the general consensus about McCann is that he was a superstar before getting is cruciate ligament done.
It kept him out for most of the first season burnley was in the prem and apparently they tried to get him back too early and he never returned to the standards he set before the injury.
Now that was their feelings before anything was mentioned about him joining Wigan.
