Ritchie is taking one for the team. Moving to an unfamiliar position while watching his future run the channels in front of him. It's got to be tough for him but he's still giving it a go, if not warming to Almiron the way we'd want him to.
I've the feeling that at this point in his career, Rafa is more keen on building a squad rather than walking into something already made. I certainly don't think he would be interested in a stress factory like Chelsea and I'm not all that sure he'd even like to manage in London. I really think that Newcastle is the apple of his eye and even a cunt like Ashley may not be able to drive him off.
As the old saying goes (here in the states), some managers are better off driving a Chevy and others are better off driving a Cadillac. Warnock is Chevy guy, Moyes is a Chevy guy. Mourinho can only drive Caddies. Benitez? He can drive anything.
