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
Almost every line in Real Madrid's team needs improvement because they have become weak and no longer look as impressive as they once did. Because if the defense isn't strong enough, the consequence is frequent goals conceded. And if the midfield isn't clever enough at making forward passes, the attack will be very chaotic and won't be able to produce on-target finishes. So, Alonso must improve all of these lines now, because he has a tough task since taking over as Real Madrid manager, and this season is his season to prove himself.
