Apparently it's "only" 130kpw.
WH offered him 90kpw and a multi year deal. Forest offered 130kpw and a 1 yr deal. He picked the latter. Not sure I can get my head round it to be honest. WH are a bigger and better club*. They have European football and will be challenging for Europe again this year. Forest will be bottom six, if not relegated. Why pick the latter?
He may play more at Forest but he's hardly gonna be a barely seen sub at WH. I guess he gets a nice signing on fee (though WH would have given him one too) and then another next year when he pisses off somewhere else.
Seems very mercenary to me.
*Yes, I know Forest have 2 European cup wins, but those were over 40yrs ago and if we count them then Forest are bigger than City, Arsenal and Spurs, and just as big as Chelsea and Juventus.
