The story behind Liverpool boss Jurgen Klopp's booking last night has been revealed.

Even if Liverpool are 5-0 up and cruising to victory, as he showed during his side's Champions League victory over Atalanta on Tuesday.

Atalanta wing-back Johan Mojica went down a little easy following a challenge from Georginio Wijnaldum, and Klopp wasn't impressed with what he saw.

The Liverpool Echo reports the German could be heard shouting from the touchline: "Are you serious!? I broke my nose five times, it was not one time a foul!"

Klopp's outburst earned him a yellow card from referee Ovidiu Hategan.
