Borussia Dortmund boss Peter Stoger has claimed that he cannot "comprehend" Pierre-Emerick Aubameyang's behaviour.
The Gabon international was recently dropped from the squad for disciplinary reasons.
The Bundesliga outfit have now taken such action against Aubameyang twice this season, but despite the off-field issues, Arsenal have been heavily linked with a swoop for the attacker.
While discussing the conduct of Dortmund's star player in an interview with Bild, Stoger said: "Disappointment is the wrong expression. Rather a lack of understanding as I cannot really comprehend his conduct, and I am certainly not the only one."
Aubameyang has scored 21 goals in 23 appearances in all competitions this season.
