Mbappe will be an important player in the Real Madrid squad, he will be guaranteed in the main squad because his quality is better than other pure strikers that Real Madrid has. Ancelotti will try to make Mbappe and Vinicius partners who help each other, this duo of players will make Real Madrid more varied and dangerous and will be assisted by Rodrygo in a 4-3-3 formation. The combination of Mbappe and Vinicius will make the opponent's defense even more tenuous, allowing one of them to score goals easily. Soon we will see the reincarnation of the BBC trio in the form of different players who will make Real Madrid even more difficult to stop.
It cannot be said for sure which formation Real Madrid will play in the next season. Madrid are most likely to play in a 4-3-3 formation. Because perhaps Ancelotti is keen to keep Rodrygo in his attack. But we saw Rodrygo miss plenty of easy chances. So Ancelotti is also likely to develop his match strategy in a 4-4-2 formation.
Ancelotti is a very experienced coach. He is very well aware of the capabilities of his squad. And accordingly he will make his match strategy. With Mbappe in the squad, Madrid's attack has been strengthened. Mbappe has the ability to score a lot of goals. The squad also has talented players like Vini and Bellingham to support Mbappe.
Carlos Ancelotti who is doing impressive job here at the Real Madrid is having now luxury of strikers which can give him their best even in last season he achieves many things without any solid striker, but now things are well settle, and he can go for any formation with most chances he will keep his 4–4–2 because in last season usually he was going with this and having good success, but now he has to adjust his all best players because this is surely a problem for him with the arrival of the Kylian Mbappé.
Rodrygo is still having strong position here at the Real Madrid but as we have few updates Liverpool and PSG both are interested with if we have any problem then surely we will have all updates regarding this because he is still young and having good career which needs to have better playing time and development which is possible at both clubs PSG and Liverpool for him.
