They don't need one if Courtois turns up with his best pair of gloves and the Real Madrid forward just continue scoring like they have always done. Alkeast Chelsea, Manchester City and PSG can attest to that.
Benzema does not need to be good the whole 90 minutes. In fact, most people are focusing on Benzema, but the Major threat is Rodygo.
^ Honestly, a goalkeeper can only do so much, and if the Liverpool forward comes with attack after the attack it will be really hard for only Courtois to stop those.
I don't doubt his goalkeeping ability but I am really concerned about the defense of Real Madrid.
and yes I agree that Benzema only needs a few changes to be the hero of Real Madrid.
The weak point is not in the goalkeeper, the occurrence of goals could be due to blunders from the goalkeeper, the rest depends on the defenders dampening attacks from the opposing team. Real Madrid and Liverpool can tire the opposing strikers with a strong defensive wall, the role of defenders can save the goalkeeper from the condemnation of supporters. The goalkeeper can do nothing if the defenders are not disciplined, as a result the goalkeeper can repeatedly pick the ball from the goal net.
