Speaking at Voetbal's studio, Koeman said: "He wasn’t in the preliminary selection because I don’t think he’s good enough at the moment. In particular, scanning when turning or passing often goes wrong. Yes, in principle, form and fitness are always leading, but that is not always possible.
"We have a lot of central defenders and midfielders, but we are somewhat limited up front. But even then, I still think that you have to earn your selection, and I think he doesn’t deserve that now, but that could be the case again in another period."
