Arsenal fans were astonished by the on-field debate between Mesut Ozil and Hector Bellerin.

Towards the end of the first half the Germany international is seen having a go at Bellerin following a delayed pass. Ozil was annoyed as the pass didn’t come earlier, resulting in him being flagged for offside.

The 29-year-old appeared to be in a rage before telling Bellerin, “You talk too much, wait until inside the dressing room.”

Ozil played a key role in Arsenal’s first two goals by winning a penalty for the opener and delivering the corner for the second. Summer signing Alexandre Lacazette netted his sides third and final goal.

Both Bellerin and Ozil are expected to be in action when Arsenal take on CSKA Moscow in the Europa League.

Winning the European competition is the Gunners only realistic route to playing UEFA Champions League football next season.
