Real Madrid had only 1 defeat this year, they are performing really well in the league. If they make one or two strong transfers next season, they will be able to really fight to be the best in the world. I think Real Madrid's current performance in the league is very good, and they can become undefeated champions after strong transfers.
In this case, Barcelona will have to work to finish the season second again

With Real Madrid's performance this season, it can be assumed that even without Mbappe, Real Madrid will still be a strong club in La Liga and also the Champions League. Moreover, the addition of Kylian Mbappe to the squad will certainly make Real Madrid a very strong club in every competition and make many clubs that face Real Madrid feel anxious and I think many clubs are afraid of Mbappe's presence in the Real Madrid squad. Next season. Real Madrid is very lucky to get good players without having to spend money on transfer fees. The combination of Bellingham, Vinicius Jr and also Mbappe will make Real Madrid unbeatable and ready to face other tough opponents, especially in the Champions League next season.
Barcelona can't do much if Real Madrid has good players in it, while Barcelona itself is unable to recruit good players, it definitely feels a lot of pressure to play against Real Madrid, let alone compete for the title. I think Real Madrid will win the title again next season because if Mbappe Already at the club, Real Madrid's performance is increasing. Hopefully Mbappe will be able to adapt quickly to the Real Madrid club.
