As for Real Madrid, we cannot deny that recruiting star players who have good quality will have a big impact on the team if it is supported by equal distribution of the squad in all lines, that cannot be denied.
Moreover, after the arrival of Mbappe in their main squad it will certainly help this team become stronger next season, I think Madrid will find it easier to win the Laliga trophy next season because Barcelona will certainly find it difficult to compete with Madrid because they seem to only retain the best players. is in their main squad and may not buy players to fill the current main squad, Hansi Flick as the new coach will certainly have difficulty competing with Madrid.
But no one knows the strength of the team because it all depends on how the coach can organize strategy and tactics when playing. I still believe that Laliga next season will still be dominated by Madrid but not other competitions such as the UCL because there will be quite tight competition. Also, it won't be that easy for Madrid to reach the UCL final again next season, even though they have new strengths which we see at the moment are quite good. Ancelotti will of course take advantage of Madrid's current strengths to be able to win the trophy again next season.
