Sport1 report that 28-year-old left-back Raphaël Guerreiro can leave Borussia Dortmund should they receive an adequate offer.
Nico Schulz (29) will also be allowed to leave the Bundesliga club after failing to impress since his €25m move from Hoffenheim in 2019.
Guerreiro has played just 19 Bundesliga games this season, missing nine through muscular problems and two after testing positive for Covid-19 in March.
The Portugal international has a contract until 2023.
