Tempers flared at the end of the first half in Saturday's Madrid derby as Atletico Madrid in particular let their frustrations show.
Vinicius Junior was at the centre of an incident on the half time whistle as he took issue with Koke's strong challenge after referee Antonio Mateu Lahoz had blown.
The confrontation between Vinicius and Koke caused a mini scuffle between the two teams, with shoves and words exchanged on either side.
In the end, the players made their way to the dressing rooms without one yellow card being shown to any of them - other than Casemiro, who had been booked earlier in the half.
