I'm sorry, but this all is genuinely ridiculous.
The player has done nothing wrong whatsoever here, absolutely nothing. He's under contract, he shouldn't be given ultimatums in public when he is maintaining his silence and getting on with his job.
Koeman is trying to villify the player and, sadly, it's working. Yes, he may go, but he is acting incredibly professionally. Not one utterance from the player or his agent, no bad words, no destabilising the club, nothing. This whole situation has got out of hand due to one person only - Ronald Koeman.
