Bosz wants Fernandez to learn from his mistakes, as the young player has already played many games and is in his first full season with the first team. "He has done well, but he still makes mistakes," Bosz said. "We have talked about it, and he will learn from it. When he plays again, he must not make those mistakes." VoetbalPrimeur reported that Bosz also hopes that the criticism of Ruben van Bommel will not affect him ahead of the clash with Shakhtar. Bosz said: "I don't know if it will have an impact. We will see in practice. I hope it won't."
