Real Madrid next season will surely be better than this season because in this transfer process they will made an effort to sign players that can really add quality to their side. Bellingham is undoubtedly a very talented player. With an experienced squad like Madrid, he will become more experienced. In my opinion, Bellingham become a legendary player for Madrid in the future like Modric. I think Bellingham has the potential. Also Real Madrid need to strong striker like Kylian Mbappé. Madrid must succeed in bringing Mbappe from PSG.
It is optimistic to say that Real Madrid will change things for the better undoubtedly because even when Bellingham is a great player who has shown his quality in many games already, Borussia Dortmund is not Real Madrid. Nobody knows whether it works from day one or whether he needs some time to get accustomed to his new teammates and everything else. But the striker position is still an open wound in the team that they need to cure most importantly. The supply side in the transfer market for high quality strikers is very thin and the players who are available are so expensive that even Real Madrid has to think avout potential transfers and first check what is possible for them.
Tuchel has a really big potential to win this title with big teams.
