It is unlikely that Real Madrid has a lot of money at the moment. You shouldn't expect big purchases. Although they can buy Mbappe. The reconstruction of the stadium is coming to an end. Real Madrid will spend another season with old players, and in a year they will make a couple of good purchases and build a new team.
I don't expect too long, I think next season they should have a good substitute. Learning from last season's problems, management should understand. They must immediately make a purchase of new players. Maybe onr season in the future Madrid will still be able to compete with some of the current players without any injuries. But regeneration is a long process, giving lessons to new players must be done by seniors.
Real Madrid should not only rely on Benzema but also added a skilled striker to the squad. They have enough money since now. Moreover, they can strengthen their defense a little more. I think their midfield is good enough. There is no need to change the midfield. They need a skilled striker.
