At least the efforts made by Benzema while at Real Madrid have yielded very good results and have been his best contribution at Real Madrid.
Unfortunately, at the moment, there is still no one who can replace Benzema at Real Madrid because the task is very difficult and not everyone can replace him easily.
It's not easy to replace someone who has contributed a lot with a club like Benzema at Real Madrid. But that does not mean there will never be players who are capable of being in the line of Benzema at the Real Madrid club, because over time there will definitely be a player who will become like Benzema at Real Madrid. Although it probably won't be in the near future as Real Madrid currently prefers to recruit young players so a replacement that can look like Benzema may not be immediately seen next season at Real Madrid.
Filling Benzema's void is difficult, but not impossible. If every player in the team is able to perform well in their position, maybe Benzema's void will not be felt. Vinicius' performance is improving. Joselu is also quite a talented player. But the main problem with Vini and ROdrygo is that they also miss a lot of easy opportunities. Expect Vini's performance to be more consistent next season. Because the team will largely depend on him in the coming season. Ancelotti is a very experienced coach. He can be trusted. He will definitely take the right decision for the good of the team. Even without Benzema in the squad, I expect Madrid's performance to be quite stable next season. Madrid's attack may be a bit slow, but their midfield and defense are still very strong.
