Ajax has confirmed that a fee has been agreed with Chelsea for the transfer of Hakim Ziyech.
A statement on Ajax's official website reads: "Ajax and Chelsea have reached an agreement for the transfer of Hakim Ziyech.
"The player will join the Premier League club on July 1st 2020 and will finish the season in Amsterdam.
"The clubs have agreed a deal of €40 million euros. This sum could potentially increase to a maximum of €4 million, with variable factors."
Chelsea, meanwhile, released a statement of their own, detailing what fans can expect from their new signing.
It reads: "A Moroccan international, Ziyech is a left-footed attacker who is comfortable playing off the right flank and coming inside, as he has often done in recent years to such devastating effect for Ajax, or on the left to attack with width and deliver into the box.
"The 26-year-old possesses awareness on the ball, is technically capable of executing very difficult passes to break down compact defences, and is also a set-piece specialist, particularly with vicious inswingers from the right side.
"He has been a prolific scorer throughout his career, with over 100 goals for club and country."
