The striker starred in the World Cup as the Atlas Lions made history, becoming the first African team to reach the semi-finals.
Ziyech had only just returned to the fold at international level after a falling out with former coach Vahid Halilhodžić. Excluded from Morocco’s squad for the delayed 2021 Africa Cup of Nations contested earlier this year, the 29-year-old has even retired from international football.
Despite being a key player for his country once again, Ziyech has always struggled to get playing time at Stamford Bridge.
A £37million signing from Ajax in the summer of 2020, the former FC Twente youngster has started just one Premier League game this season and has already attracted interest from AC Milano.
Chelsea will further strengthen their frontline with the summer signing of RB Leipzig and France striker Christopher Nkunku, while Molde teenager David Datro Fofana is also expected to join.
As a result, Regragui told Ziyech to find a new club in order to secure first-team football.
“[Selim] Amallah and [Azzedine] Ounahi will surely find better clubs and the same for Ziyech, who has shown what he can do, he deserves to start at Chelsea,” he told Viola News.
