Real Madrid have added Mbappe to their squad this season. The addition of Mbappe has forced Madrid to make major changes to their match tactics and formation. And it is normal that it will take some time for the players to adapt to the completely new formation and tactics. This is why Madrid's performance was somewhat erratic.
Madrid made the right decision due to the addition of Mbappe to the team. The gap in the team is expected to be filled quickly. Since he is a legendary player his strategy will definitely be different. In the light of his experience, there is also a natural change in strategy. Moreover, it is true that a good player cannot give his best just by joining a new club. This requires time and patience. At the beginning of the season, Madrid did not perform as expected, but currently the club is moving towards improvement. At this time, Barcelona's only rival is Real. I believe Real will occupy Barcelona's place at the moment. At this point in the points table, Real is behind by only 3 points. Next October 27, Real will try to level on points in the table or they will fall behind. Which team is the best will be proven at that time.
Mbappe is a world-class player who has made many achievements with his club, so it is natural for Real Madrid to bring in Mbappe. The reason is, Real Madrid is always able to bring in star players. Good examples include Ronaldo, Roberto Carlos, Kaka, Beckham, Eto'o, and many others. So in essence, the Real Madrid analysis team is very clever in selecting the players they bring in and apart from that, Real Madrid's finances are always stable. That's why Real Madrid is always able to bring in great and very expensive players like Mbappe.
Mbappe is currently unable to show his best performance. But sooner or later Mbappe will definitely be able to bring out all his best abilities for Real Madrid.
Then talking about Real Madrid's match against Barcelona, I personally am quite worried about Real Madrid. The reason is that currently many Real Madrid players are injured. For example Courtois, Lunin, Vinicius, Militao, Alaba, Carvajal, Brahim Diaz and Dani Cebalos. So with this I am a little worried about Real Madrid, especially now that both Real Madrid goalkeepers are injured. So, for example, Real Madrid's injured players have not recovered during the match against Barcelona. Most likely Real Madrid will lose to Barcelona. Because currently Barcelona's performance cannot be underestimated, so if Real Madrid plays with a less than optimal squad, I'm sure Real Madrid will have difficulty getting points.
