There have indeed been changes in the Real Madrid squad between last season and this season which has just finished. Last season Vinicius Jr struggled very hard on the front lines
without good support because at that time Benzema was still there but rarely played due to injury. But this season Bellingham came to the Real Madrid squad and scored many goals for Real Madrid and Bellingham helped Vini Jr a lot on the front lines. And next season the Real Madrid squad will be different again with the presence of Mbappe.
Regarding Barcelona last season, they were great in La Liga but bad in the Champions League because they failed to qualify for the group. But this season, Barcelona went quite far in the Champions League but lost the competition in LaLiga to Real Madrid. And was even overtaken by Girona. But Barcelona managed to improve things at the end of the season so they managed to return to second place. But I'm not sure what Barcelona will be like next season.
The arrival of Mbapp to Real Madrid has brought an end to the drama surrounding his move. His decision not to request the number 10 jersey out of respect for Luca Modric, who has been a legend at the club, speaks a lot about his humility and admiration for the team's stars. He rather opted for the number 9 jersey showing his readiness to go on his own path while honoring the club's history.
Thoughts about the formation under Ancelotti after Mbappe's arrival are wide, with many suggesting a switch to a 4-3-3 setup with Mbappe as the central striker. Ancelotti's silence on the matter shows that no decision has been finalized. Mbappe's eagerness to join Real Madrid comes not only from the feeling of wearing the famous white shirt but also from his desire to clinch the prestigious UCL trophy. With Real Madrid's history in the competition, Mbappe sees the club as the right place to fulfill his ambitions.
Ancellotti's boy have always had a good game for the team even though more than much is been expected from them but for a game in a every competition, they always did really good. This only resonates the sermons of how well built up Real Madrid squad is. The young players are definitely an extra advantage to the team's strength.
