I think it may work out well for him there. A fresh challenge, good manager. He will bring them something new and plenty of experience at the same time. It will be interesting to see how it goes. A parting after so many years was never going to be painless but you can't blame a bloke for wanting to make a bit extra and something new whilst he still has it in him. It's either move or stay and slowly retire (not sure clubs do this so much anymore). I wish this had been done in the summer though, a quick split would have bee better for all.
