Yeah they were struggling from the group stage.
Few match ended dramatic because they won by comeback in the last minutes, they even an underdog in final match, really crazy to follow how Real Madrid can become a champion.
I think Ancelotti will take a big move, which is put Mbappe on bench.
Putting Mbappe on bench... It would be a huge move if Ancelotti does something. But I don't think he will do such thing. He is backing up Mbappe in his struggling times recently. It would be surprising to see him making such decision as a result.

Mbappe scored a goal in his last game. Maybe this would be some extra motivation for the Champions League game against Atalanta up next. It had better be some help for him.
By the way Vinicius Junior is back or not? Some sources say he is ready but some say the opposite.

Mbappe was Ancelotti's favourite player now. It sounds impossible to see him bench Mbappe especially on this important match. I really appreciate if he does something different like bench mbappe on the UCL game. *LMAO
Can we really able to use his scoring against Girona as a benchmark to determine his performance? I personally would not do that. Girona was a weak team, and totally different with Atalanta. A club that is topping serie A now.
As for Vini, he has been included in the line up against Girona, and i think he will start.
