Hakim Ziyech completed his transfer from Ajax to Chelsea in July 2020, making him eligible to play for the team as of the start of the 2020–21 campaign. He had previously given his approval to become the team’s first international from Morocco in February after signing a five-year contract.

The attacking midfielder, who plays primarily with his left foot, caught attention with the way he played, cutting in from the right wing at Ajax. However, he can also play as a more regular winger on the left or in the middle, supporting a striker.
