That mountain you're stood on looks an awful lot like a molehill from over here.
Manager demands extra work from players shocker. This really is a complete and utter nothing story. Every single manager uses varying methods to push their players. To get that extra 10% out of them (to use a shite cliche).
Of course the conversation has been had in private with the players, it would be naive to think otherwise. Saying it publicly by no means constitutes unprofessional behaviour, it's merley reflective of his honest persona, which some find too honest.
Koeman publicly called out Barkley's workrate and by jove, it motivated him.
Every manager does have and use a range of methods or tools, which is why publicly shaming is one of the last tools used. He's not challenging a player to deliver a better performance as a chance will come soon, he's saying they're unlikely to get a chance. If he's using it as a motivational tool, he's a desperate moron, the more likely motivation is defending his own reputation and trying to downplay his own responsibility, it's up to players, not my fault gov, same with performances.
Presumably he's talking about Klaassen, Vlasic, Sandro. If he's not going to use them, then why bother. If you plan to use them, then try and integrate them into the team, build their confidence, not shoot them down while they're struggling. And I said he's calling the players unprofessional.
As Lionel Hutz would say there's the truth and then, there's the truth. The glass is both half empty and half full, it depends on perspective. But it certainly seems to be a growing trend for islands of irresponsibility. That if someone is ignorant enough, it seems to remove any liability for their actions or stupid statements. It's that refreshing honesty about how shit everything else is, that paints them in a good light. I'm just surprised how many seem to lap it up, well it's true, yes but it's his job and he appears to accept no responsibility when it goes wrong.
