I think that the main problem for Real last season was their defense, because their attack played quite well. Even when Mbappé or Vinícius were injured for some time, they replaced each other and the attack performed quite well. Last season there were very big problems because they lost two key defenders, Carvajal and Militao were missing, and they conceded too many goals. If you remember the matches against Barcelona, it was Real?s defense that let them down.
So historically Real Madrid's defense has always been an attack, it has never had an exceptional defense but it has always applied attacking pressure in this way both the defenders and the goalkeeper have never had too much work to do.
The Dribbling has helped a lot in managing the games but lately it seems to have been lost, which is why the defense suffers in my opinion
