The truth is this player is impressive, his ability to integrate into such a group, which at first glance seemed to have not accepted, was simply magnificent and made the whole world yesterday bow to the best player of all currently ( The football world of course)
Mbappé's name is now all over because he make an incredible performance in their last match against Manchester City. He has joined the players that have successfully secured hat-trick against Pep Guardiola teams, the gangs of Agüero - 2014, Messi - 2016, Vardy - 2016 & 2020, Nkunku - 2021, Gyökeres - 2024 and Mbappe - 2025, this was a nice achievement for him because not all reputable players can do it. His performance also won him best player of the week. I have full confidence in him that he will fill the gaps he is expected. Jude Bellingham is contributing a lot for Mbappe success, Jude Bellingham have the highest assists more than any other players in the Champions League since last season.
Mbappe is starting to find his best place again and Real Madrid are really very happy with his actions. It is not easy for some players to be able to score a hat trick in the Champions League and Mbappe is able to enter the group of strikers as you mentioned. Thanks to that success, Madrid has a great opportunity to continue to go far and of course Mbappe really wants the Champions League title so he is very motivated in every match he goes through.
