Chelsea are set to sign winger Hakim Ziyech from the Dutch champions Ajax this summer.
The 26-year-old was a January transfer target for Chelsea boss Frank Lampard.
Ajax were unwilling to sell the Morocco international in the transfer window as they chase the Eredevisie title but on Thursday they confirmed the deal.
“Ajax and Chelsea have reached an agreement for the transfer of Hakim Ziyech. The player will join the Premier League club on 1 July 2020 and will finish the season in Amsterdam,” the Eredivisie outfit said in a statement.
“The clubs have agreed a deal of €40 million euros. This sum could potentially increase to a maximum of €44 million, with variable factors.”
The signing is the first by Lampard following Chelsea’s transfer ban.
Ziyech contributed to three Ajax goals in a 4-4 draw against Chelsea during their Champions League group game in November.
