Real Madrid was just completely destroyed by PSG at the FIFA Club World Cup. Before the match, the French team was considered stronger as the reigning UEFA Champions League champions with convincing play. However, no one thought Real Madrid would be defeated so easily.
In just 24 minutes, PSG scored 3 goals very easily against Thibaut Courtois. If the remaining shots had been adjusted better, the match could have ended with a result of 7-8 goals in favor of the French team. PSG has completely surpassed, currently the strongest team in the world.
Among the many reasons for Los Blancos' failure, the couple Vinicius Jr and Kylian Mbappe received a lot of criticism. They are the biggest hopes but play sluggishly, lacking vitality in many situations on the field. Both have strength, speed and the ability to decide on situations, but they have not been shown.
While PSG players pressed continuously all over the pitch, Mbappe and Vinicius walked slowly, making many Real Madrid fans feel frustrated. If we use the reason of hot weather as an excuse, it will be very difficult to convince because PSG's attacking trio has recreated the form that has sunk European football last season.

This was once a problem for Carlo Ancelotti but this veteran strategist could not handle it. Since Mbappe joined Real Madrid, there have been many questions about how Carletto would handle both Mbappe and Vinicius on the pitch because both have the ability to play on the left wing? In some games, everything seems fine but in the end it got there.
This task is now in the hands of Xabi Alonso. The Spanish coach bravely took Rodrygo off the plan when the young Brazilian striker failed to meet the requirements. Rodrygo was once a ministriesman in the Galaticos 3.0 plan but is no longer in a position.
With Vinicius and Mbappe, Alonso is forced to make a choice. Either Mbappe is still playing as a center forward, or both will be on the same left wing. At that time, one of the two had to leave the team.
For Xabi Alonso, the personnel to replace Rodrygo are considered available but finding a replacement for Vinicius or Mbappe is almost impossible at this time. Before Mbappe's arrival, Vinicius was the main star, almost invincible. In the last two times Real Madrid won the Champions League, the Brazilian striker played very well, so he is considered the hero of Galaticos 3.0.

Since Kylian Mbappe's arrival, the French striker has been considered the number 1 star. Mbappe is a case that president Florentino Perez himself is pursuing, so it is difficult for Alonso or someone to put the French striker off the plan. In last season, while Real Madrid were left empty-handed in all competitions, Mbappe still won the European Golden Boot. Therefore, Mbappe is now considered an award-winning attacking player.
If Alonso cannot solve the problem of motivation and coordination between Mbappe - Vinicius, Real Madrid will pay the price next season. Looking at other strong opponents, the attack is distributed very evenly. There are teams with shared roles like PSG and Barcelona, there are many teams focusing on just one spearhead like Bayern or Man City, no team falls into the current situation like Real Madrid.
Mbappe and Vinicius are very good but they also have a big ego and want to be the number 1 star in attack. This is the biggest problem Alonso has faced since his time as coach at Los Blancos.
