I believe the average wage for a GK coach in the PL is somewhere around £150k a year and I imagine he'll triple that in Chelsea.
The difference between £150k and maybe £500k... could you really blame him for going or GP for asking if he'd be interested in that?
Yes, brought him to Östersund...
While I understand it, I'm a bit disappointed in his decision.
As for the other part, I think it would be incredibly low not to ask them when they have been a huge part of his success.
