Arsenal players looked fired up ahead of their clash with Manchester United on Wednesday.
Pierre-Emerick Aubameyang posted a video on his Instagram page of Shkodran Mustafi and Mohamed Elneny playing table tennis.
It looked as though the match got a bit heated as Aubameyang captioned one of his stories 'aggressive' when Mustafi hit the ball.
The German defender's aggression appeared to pay off though as he won the first encounter between the pair.
Aubameyang teased his colleague Elneny and wondered how he lost the match.
