Former Ajax winger Kenneth Perez admits he's a big fan of Frenkie de Jong.

The Ajax midfielder, reports Voetbal International, is being watched closely by Chelsea, Manchester City and Bayern Munich this season.

"I understand that people are getting tired of it. Frenkie de Jong, Frenkie de Jong. He has played five or six times. But I am so bothered by him because he shows things that you hardly see in others," says Perez.

"He can delay things. He likes to wait until there is a better option, and if it is not there the ball can go back. He does not quickly panic. He wants to play everything forward. The players who play with De Jong also know that."
