Asked about the situation, Van der Gijp said on SBS6: "Well, well when Frank Lampard was still the trainer, he was very enthusiastic about him.
"And then another trainer comes (Tuchel) and he wants to play a different game. He really wants to have runners in his midfield, instead of people like Ziyech. And then you have a problem.
"He needs to leave.
"That would be best for him."
