The Morrocan is set to join the Blues on July 1 after agreeing a £37.8million move in February.
Ziyech says he has been a fan of the Premier League for years and has set his sights on replicating one of the league’s best ever players.
“The Premier League is a great competition, especially because of the fast thinking, technical players,” he said.
“As a kid, I’ve always dreamed about this. I watched the games Chelsea, Arsenal and Man Utd played and players like Didier Drogba, Thierry Henry, Dennis Bergkamp and David Beckham, you name them. I want the same thing.
“Is it the best competition in the world? I don’t know. I also admire La Liga, but the Premier League is definitely the most intense.
“I don’t like to take the easiest way, because you’re not challenging yourself when you do. I like challenges. Those make me stronger and keep me sharp.”
