"He will be looking to leave Chelsea in January," reliable reporter Matt Law told the London Is Blue podcast of Hakim Ziyech.
"The AC Milan interest may have redeveloped once again and a good World Cup can spark a little bit more interest in him."
Ziyech is having a good World Cup with Morocco, winning the Man of the Match award in his side's 2-0 win against Belgium.
The 29-year-old has made just nine appearances for Chelsea so far this season, failing to record a single goal or assist.
He was expected to leave the club last summer but a move to AC Milan failed to materialise.
