Hakim Ziyech would force an exit this summer.
The Moroccan international started only five Premier League games this season, three of those came in his last four games.
He has fallen down the pecking order under several managers and could be offloaded in the summer by the West London club.
The 30-year-old has contributed to only 25 goals across three seasons and was closest to leaving in January.
The former Ajax winger has often cut a frustrated figure at Stamford Bridge and has not featured since the end of February.
He was close to signing for PSG in the January transfer window but the move failed to materialise in the final moment.
Club legend Frank Leboeuf believes Ziyech should leave in the summer.
Lebouef told ESPN: “Well, definitely Ziyech. The guy is not happy, and he wants to work. Every time he plays for Morocco, he’s the best player in the world, and every time he plays for Chelsea, he feels sad and lost.
“So I wish him to go somewhere else where he can show to the world he’s still the Ziyech that we have seen when he played for Ajax.”
