Nobody said Courtois was bad because it was very clear that in terms of goalkeeping at Real Madrid, Courtois deserved a lot of appreciation because his saves were extraordinary, but it would be very complete if Real Madrid's defensive line became stronger again. So a goalkeeper like Courtois won't be too tired in saving a ball shot at goal directly.
Yes, that factor is what causes Real Madrid's defense to not work. But if we look at the overall game I think Real Madrid's defense has done well. It's just that when the goalkeeper made the save it was more highlighted because it was the last save from the players. But it's also not wrong for Real Madrid to be better able to improve.
