Real Madrid do not want to spend money on a goalkeeper at the moment as they may have to spend a lot of money next season. Real Madrid has a big chance of signing Mbappe next season, so Real Madrid must have enough money to complete the deal with Mbappe. In the absence of Thibaut Courtois, Real Madrid already have a number of goalkeepers, and with Real Madrid bringing in Kepa Arrizabalaga from Chelsea on a season-long loan, it doesn't make sense to spend extravagantly on a goalkeeper at the moment. If Kepa Arrizabalaga is not injured, he will be seen as the main goalkeeper for Real Madrid throughout the season.
Elite clubs will compete with strong hand this season. Real Madrid is an elite team, they have the capacity to grab any player that's table on the market. Talking about spending their estimated budgets on players this season is balanced, they keep track on every player in the team, moving to a more crucial point. Perhaps Carlo Ancelotti looking for options to explore this season, their top choice was injured but instead of signing a permanent signing, they signed a temporary backup goalkeeper on loan this summer, inother to fixed the goalkeeping challenges.
