Boudewijn Pahlpatz is backing Hakim Ziyech to be a big hit with Chelsea.

The Ajax midfielder will move to the Blues this summer for a fee rising to €44m.

Pahplatz, who coached Ziyech while he was at Twente, said: “He has played in the Eredivisie for seven or eight years now.

“The step to the Premier League will do him good. He will be playing with the best players every day and that is a new challenge for him. He will do well there.

"He will have to get used to the amount of games and the physical side but in the end he will succeed, for sure."
