Chelsea attacker Bertrand Traore angered his Ajax coach Peter Bosz on the weekend.

Traore upset Bosz with his showboating in victory over ADO Den Haag.

"That bothered me," Bosz told FOX Sports. "It was unnecessary, because there was so much space on the field.

"When you play with the ball like that, you can get kick. He got kicked a few times. But, he'll learn from it. He is still young.

"It is not right that he gets kicked, but it makes sense.

"It is a way to learn. He should not, but in training I also do not whistle. And so the referee did not. So in that respect it's fine."
