Dusan Tadic, who scored 20 goals in 134 Premier League appearances during his four-season spell at Southampton, believes that his teammate will succeed at Chelsea.
“I know from my own experience that the Premier League is a tough competition,” the 31-year-old told De Telegraaf.
“But I hope and count on Hakim to succeed because he is a quality player. And Chelsea seems to be a club where he fits well because it is an attacking team.
“Hakim comes into its own in this. I hope we can all give him a nice farewell: with three prizes.”
Ziyech has been sensational for Ajax. Since joining the team in August 2016 in an €11m move from Twente, Hakim has scored 48 goals and provided ridiculous 82 assists in 160 games.
Last term, the Moroccan has won a well-deserved Eredivisie Player of the Year award, led de Godenzonen to a domestic double and reached the Champions League semi-final with the team.
Since the beginning of the 2018/19 campaign, the 26-year-old scored 29 goals and registered 45 assists in 80 games across all competitions for Ajax, including 8 goals and 21 assists in 31 matches this season so far.
