The coach of Atletico has recently distinguished himself in the match of his team with Juventus. After another goal was shit against opponents, Diego Simeone turned to the “Wanda Metropolitano” stands and showed an indecent gesture, seizing his groin.
To say that some fans were shocked means to say nothing.
UEFA couln't close its eyes to such things, and it was offered to open disciplinary proceedings against Simeone.
If it's decided that the gesture of the coach of Atletico was offensive, it is quite possible that he will be sent to the ban.
