Many people's expectations may be like that, but I don't think that Real Madrid will be unbeatable in these two competitions next season, because the arrival of Mbappe into the Real Madrid squad is indeed good for adding to Real Madrid's own strength on the front lines. However, Mbappe himself must also be able to adapt himself to the Real Madrid players and must not be selfish when he is there next season. I also see Real Madrid as a candidate team to win in the two big competitions, but in terms of being undefeated, I think that is a bit difficult for Real Madrid to achieve.
In a team full of star players, it is certainly very difficult for anyone to stand out and instead of prioritizing winning, sometimes they will be more selfish when it comes to scoring goals when they have the opportunity. Maybe here it is very appropriate to see what Real Madrid will look like next season, of course this situation must be immediately conditioned because it is so important for the harmony of the dressing room.
I think Mbappe must be well aware that here no player is more important than a club's victory, therefore when he has the opportunity to pass instead of scoring a goal himself which may not necessarily be a goal then he must provide an assist to his partner. This also applies to other players and I think that in Ancelotti's hands the situation will be quite conducive and they can focus again on winning the Champions League title.
