Ajax legend, Marciano Vink believes the likely return of Hakim Ziyech could cause problems for the club.
According to Marciano, the club has enough players in the role Ziyech plays including Ghana's Mohammed Kudus.
Reports indicate the Morocco winger is set to retun to Ajax after struggling to establish himself at Chelsea.
"You already have quite a problem in the front with who should play where and who is second or third choice? You already have Berghuis, Klaassen, Kudus and Tadić.
"It doesn't solve the problem of the other guys walking around there, who also want to go to a World Cup," said Vink on Veotbal Talk on ESPN.
Meanwhile, Mohammed Kudus is reportedly on the radar of English sides Leicester City and Everton and could make a switch in the summer transfer window.
Kudus has struggled to make the starting XI of the Dutch champions in the ongoing season.
