You will most likely be punished financially.
Luis Enrique could be punished for the unfortunate incident at the end of the game at the Metlife Stadium. If the coach's actions are considered serious, the sanction can be transferred to both Ligue 1 and the Champions League, a very difficult situation to reach. The referee of the match and what he wrote on the score sheet will have the last word. That will be the starting point that FIFA will use to assess and quantify the actions of the coach, but whether or not he is punished will be seriously damaged in the world of football.
What the PSG coach did, FIFA hurt. That is the reality. He will most likely be fined, because if the attack is small or not very serious, the match-time penalty would be aimed at the next club world cup. It does not seem to be in any way that the possible punishment can be transferred to domestic or continental matches, given the nature of the punishment: not overly serious, but not at all constructive.
What was not fun at all was his reaction after a match that was lost by PSG, although, while known that his first intention was to separate, the truth is that he put his hand to the body of Joao Pedro with a little more intention than that of avoiding a fight.
Within FIFA it is surprising that a coach would jump into a fight and actively participate. It was a world cup final and such behavior is not suitable for someone who should lead his team in a sporting way.
