Former Chelsea assistant manager Henk ten Cate is backing Ajax midfielder Hakim Ziyech for success with the Blues.

It was confirmed on Thursday that Ziyech would be joining Chelsea at the end of the season for a fee rising to €44m.

"The game in England is a lot more physical and he will have to arm himself against that. But his football qualities are beyond dispute," Ten Cate told De Telegraaf.

“And especially because of the mental aspect. At the time he had manners, but he has grown completely over it.

"Ziyech has grown up, he's a personality. That coupled with his special football qualities makes him a top player."
