Koeman can't really win, you're right, for a couple of reasons I think..
He did (noone can logically disagree with this), go out of his way to talk about Ross, a lot, in comparison to others.
The 'board' should have had the contract done and dusted before Koeman arrived. Like they did with Gibson and Koeman agreed to the contract extension for him, even though (as proved later), he wasn't part of his plans.
This should've been handled better.
So why are people slating Koeman? what do you actually want him to do? allow Barkley to run his contract down if he is not signing it or sell him?
