Mesut Ozil said farewell to White Hart Lane by taking his Arsenal frustration out on a door in the aftermath of the final north London derby to be played at Tottenham Hotspur’s traditional home.

While Ozil failed to make an impact on the pitch during Arsenal’s 2-0 defeat, the German made his mark off it amid growing doubts over his future.

Ozil reacted furiously to being told he must take a drugs test after Tottenham’s comfortable victory and initially attempted to refuse to go through the timely procedure.

Witnesses claim that after being told he could be fined, Ozil kicked a door in frustration, leaving his stud marks on it, before begrudgingly agreeing to be tested.

It is understood that Ozil was unhappy with the number of times he has been nominated for drugs testing this season, although his anger also points towards a wider frustration.
