The reason is the incorrect behavior of the players, the provocation in the match of the 1/8 finals of the Champions League against Madrid Atletico, which took place on March 12 (1-0 in favor of “creamy” and victory in the penalty series).
The initial decision made by the UEFA Disciplinary Committee in April provided a fine of 40,000 euros for Rudiger and 30,000 euros for Mbappe, with both players received a conditional disqualification for one match – which meant they would serve disqualification
Only in the case of recurrence of a similar violation in the future.
Sebalos, which was not part of the team that day, but joined the celebration on the field, was fined by 20 thousand euros.
The UEFA Inspector of Ethics and Discipline concluded that several Madrid players acted in a manner that did not meet the expected standards of sports behavior. The governing body pointed to provocative gestures and chaos as long as Real Madrid players celebrated their qualification.
After considering all the case file, the appeal of the Madrid club was rejected and the punishment remained in force.
