I think Bellingham's absence will have a significant impact on Real Madrid's performance. Although Real Madrid has players ready to fill the void while Bellingham is absent, it's highly unlikely that those players will be able to match Bellingham's contribution to Real Madrid's midfield. Therefore, Real Madrid's performance will likely decline slightly due to Bellingham's absence. However, this is unavoidable, as if Bellingham continues to endure the pain of his shoulder injury, it could have serious consequences. Bellingham has been nursing a shoulder injury for two years now, so postponing surgery is no longer an option. Therefore, Real Madrid must utilize the existing midfielders effectively. Xabi must also devise the right strategy to ensure Real Madrid's performance remains strong, even without Bellingham in the squad. And according to reports, Bellingham will indeed be recovering until October, but I personally think it could be longer. Because of the shoulder injury, his recovery will undoubtedly be quite lengthy.
Some people still claim that Real Madrid doesn't need any midfield signings that it's only defence they should sign, to further back their argument, they referred to the news of Real Madrid not signing any players again this summer. I just laughed, because they took that news to heart too much. I asked, as Bellingham is absent now, which Real Madrid current midfielder can take his place! No response. They just forgot that the game of football is played in the midfield, who ever controls the middle, controls the entire game.
