An argument arose between the technical directors, when Arteta objected to not giving Liverpool player Sadio Mane a yellow card, after a violent clash with Arsenal defender Takehiro Tomiasu.
Klopp was very angry after Arteta’s objection, and went towards the Spanish coach, but he was satisfied with verbally clashing with him, to which the Arsenal coach responded in kind.
The incident increased the tension of the meeting, whose first half ended with a Liverpool goal, scored by Mane.
Immediately, referee Michael Oliver issued two yellow cards, one for Klopp and another for Arteta.
