Although it is common knowledge that Real Madrid needs a striker to match Karim Benzema's calibre, I don't believe this will have a huge impact on the squad because there are other young players who can fill the role just as well and who, like Rodrigo, are also capable of scoring goals.
We all understand that Rodrigo is a striker, but some have questioned if he would contribute as much to the team as Kareem Benzema, who is known for being highly active. If you look closely, you'll see that Real Madrid is still interested in signing Mbappe and has spent a lot of money to do so, but PSG insists that they don't want to give him to them for free. This indicates that the player is excellent and will perform well for real Madrid the way he did for PSG, but if they truly believed that Rodrigo would fulfill Kareem Benzema role for them, they wouldn't be searching for Mbappe nonstop. In my perspective, they still need another striker so they have backup in case of injuries.
