Arsenal are keeping a close eye on the development of Konstantinos Mavropanos.
The Greek centre-back has impressed mightily in 13 appearances with Stuttgart this season.
The Gunners are aware that other clubs have taken a liking to the 23-year-old and are continuing to watch his progress, according to football.london.
A decision will need to be made on Mavropanos when he returns to the Emirates this summer.
Mikel Arteta has a glut of centre-backs at the Emirates, including Gabriel, David Luiz, Pablo Mari and Rob Holding.
