Mesut Ozil was involved in angry scenes following Sunday’s 2-0 defeat to Tottenham at White Hart Lane, according to The Telegraph.
The report claims the Germany international was furious after being informed he must take a drugs test after the game and initially refused the request.
Ozil then kicked a door in frustration, leaving stud marks on it, after being told he could be fined if he did not comply before reluctantly agreeing.
The Telegraph claim his actions show his huge frustration at the current situation at Arsenal although he was also upset at the number of times he has been tested this season.
Ozil put in another below-par display on Sunday with the World Cup winner struggling for form in 2017, although he is not the only Gunner who has failed to impress recently.
Recent reports have claimed Fenerbahce are interested in the 28-year-old although Arsenal want at least £42.2m if they are to part ways with Ozil.

Ozil is yet to agree a new contract at Arsenal and has previously stated he will only stay at the club if Arsene Wenger remains as manager.
The Frenchman is yet to confirm his future although the current expectation is that he will stay on and sign a new deal to remain at the club.
Ozil is believed to be demanding huge wages to stay at Arsenal although Wenger stated recently any contract talks have been put on hold until the end of the season.
