Quote ="RogerMoore"Wane has only ever coached 1 club team - Wigan. The man is Wigan through and through. Would he bring the same desire to another club?'"
Don't really see this as a problem with professional sportsmen. They're not quite like fans.
It's a job to most of them and the cost of doing it badly is their job and reputation. It being a club that were once their rivals seems of secondary importance to ability and personal determination/resilience/motivation.
In other words, if he fails, it won't be because of Wigan-Warrington tribalism.
