Bayer Leverkusen coach Peter Bosz fears Ajax midfielder Frenkie de Jong could become a target for hatchet men.

On his way to Barcelona in June, De Jong is suffering just like Diego Maradona argues Bosz, who worked with the midfielder when coaching at Ajax.

"I thought Frenk was running too much with the ball. The consequence of this is that you get a kicking. You can see that now: every game it happens once or twice that he gets kick. A big kick. I'm afraid that it could be the same as Diego Maradona," he told Voetbal International.

"He says: 'That's what I like, to feel the opponent for a moment'. I said, 'Frenk , I know it's harder nowadays, with those cameras, but if I had met you as a player, I would have taken you, man and ball'.

"Watch out: every game it happens to him. Against Germany, against France, and then you see him angrily looking at the ref. Because he gets so many kicks. But I say: 'Frenk, sometimes you come into a duel and it happens, but with you it is nine times out of ten, so move the ball quicker and you have no contact'."
