Former Holland star Rafael van der Vaart says Ajax shouldn't be moving for Chelsea midfielder Hakim Ziyech.
As they sell Antony to Manchester United, Ajax are in talks to sign Ziyech as a replacement.
But Van der Vaart says: "But now that Antony is leaving, I think it makes more sense (the transfer from Steven Bergwijn from Tottenham) and so you shouldn't get Ziyech, I think.
"I say that while I am Ziyech's biggest fan. But you create another problem."
Karim El Ahmadi, who was a guest on Studio Voetbal, however said: "I am a fan of Ziyech, so if you can still get him...
"I do have some contact with him, but not very much. We often played together for the Moroccan team. I haven't talked to him about a return to Ajax yet, but I do think he could be a player who can help Ajax further."
