The coaches turned to see what was going on and were quite surprised
In stoppage time, with Atletico Madrid looking for an equaliser, Stefan Savic and Ferran Torres clashed. The referee Munuera Montero sent them both off.
Xavi and Diego Simeone, focused on the action and the ball - far away from the fight - turned and were stunned by what they saw.
Cholo had his hands to his head, Xavi had his wide open. In the moment they did not understand what was going on.
Their assistants were quicker to react, making sure the players went to their respective dressing rooms without continuing the fight.
A battle that suited Barca better in the end, as they had the lead.
Between Xavi and Simeone there was respect. The Argentine, who usually sprints off down the tunnel at the end of games gave Xavi a hug before he went.
