With all this talk of 'ultimatum' and 'public ultimatum' I think people would benefit from re-reading these quotes by Koeman.
"It was no ultimatum. But football is a business," Koeman said. "I think the player needs to understand this, it's not an ultimatum but I spoke to Ross about a new contract and it's up to the board to get that over the line. If not then the player could see a new future for himself, but that is normal, it's not strange talk.
"At Southampton we had Clyne, he did not have a new contract and we sold him. The player has to understand that if he doesn't sign a new contract, he needs to make a decision for the club so that they know what happens next year. Ultimatum is strong, I don't like that word."
