Jesper Gronkjaer once completed a move from Ajax to Chelsea back in 2000, and the 42-year-old former Denmark international has warned Ziyech that the Premier League is more physical and faster than the Eredivisie.
According to Gronkjaer, Ziyech must be mentally prepared to face the challenge of the Premier League which is very different than what he’s used to in the Netherlands.
“Adapting to the Premier League is more of a mental challenge than anything else,” the 42-year-old told Goal.
“When you play for Ajax, Feyenoord or PSV then you are at teams that dominate possession, create chances and score lots of goals all the time. There’s a lot more space too.
“Now, in the Premier League, the learning curve isn’t there and you have to produce from day one. It is more physical and faster but now compared to my day, it is more technical. You have lots of skilful players and every team have great technicians which makes it easier.”
