The Portuguese international joined Chelsea last summer for £45 million but has made only a limited impact. He played just 12 Premier League games in the first half of the season before being sent on loan to AC Milan, where he made three goal contributions in 21 appearances.
Felix is reportedly keen on returning to Portugal, where he may reunite with his former manager Bruno Lage. This would suggest that a move back to Benfica is likely, with Maresca not selecting Felix for the Club World Cup squad and no plans to use him in the future.
Chelsea would lose around £10 million on Felix if they sell him for £35 million, which would be a significant financial blow. The Club is trying to balance its books and get rid of other players who will not feature in the new season.
