UEFA's investigation into the celebration behavior of Real Madrid players after the victory over Atletico Madrid has been officially opened, and the media from Spain have posted a video of the celebration after the game. Through the video footage of the game, it can be clearly seen that Mbappe shook his private parts with his hand in front of the stands, and this behavior was recorded by the camera, and it is likely to be punished heavily.

歐足聯對於球員的不雅慶祝行為還是管理比較嚴格的，多名球員都曾因為類似的問題遭遇歐足聯的處罰，皇馬球員貝林厄姆在去年的歐洲杯就曾因為類似的動作被禁賽1場。在去年歐洲杯的1/8決賽當中，貝林厄姆幫助球隊拿到比賽勝利之後，曾經對著斯洛伐克的替補席做出了同樣的不雅行為，最終歐足聯調查後判決1場比賽的禁賽，以及罰款3萬歐元的處罰，不過這一處罰並沒有立即執行，而是1年的緩刑。

3萬歐元的處罰對於姆巴佩和皇馬來說都不是太大的問題，僅僅是姆巴佩一周的薪資就足以覆蓋掉這個數位，只不過禁賽對於姆巴佩和皇馬來說是比較難以接受的結果。由於姆巴佩的行為發生在歐冠的比賽當中，禁賽也大概率需要在歐冠當中執行，而接下來皇馬需要面對的是1/4的決賽對手阿森納，如果姆巴佩被禁賽的話，對皇馬的陣容實力還是會造成不小影響的。

At present, the results of the UEFA official investigation and punishment measures have not been officially announced, referring to the results of the punishment against Bellingham last year, the ban of 1 years plus the fine will be a relatively reasonable number, if the final punishment is according to the penalty against Bellingham, it means that Mbappe will miss the first leg with Arsenal. With Real Madrid and Arsenal playing away and then home, even if Real Madrid are without Mbappe in the first leg, the French striker can play at home and help Real Madrid win the game against Arsenal.

After Mbappe joined Real Madrid this season, he experienced a short period of adaptation and quickly became the absolute core of the team. Even before the end of the season, Mbappe has scored 4 goals and provided 0 assists in the league and Champions League games, and is one of the team's best performers. If Mbappe is punished, Real Madrid will need other players to step up and help the team win the promotion, and for Mbappe, if he is really suspended, he needs to take a warning to avoid similar problems again.
