Mavropanos is currently on loan at Stuttgart and has made 10 appearances for the Bundesliga outfit during the 2021-22 campaign, scoring four times and providing one assist in the process.
According to football.london, the German side have an obligation to buy the centre-back for €3m (£2.5m) when next summer's transfer window opens for business.
The report, meanwhile, also claims that Guendouzi's €11m (£9.5m) permanent move to Marseille will go through providing that the French outfit are not relegated this season.
The Gunners allegedly have the option of recalling the Frenchman, but head coach Mikel Arteta does not view the midfielder as part of his plans moving forward.
Mavropanos has been with Arsenal since 2018 but has only made eight first-team appearances for the club, while Guendouzi featured on 82 occasions for the North London outfit between 2018 and 2020. body check tags ::
