The match against Barcelona is not a reference point but Madrid must feel that it will be difficult unlike the initial expectations.
unfortunately it is something that should be taken as a reference because it was not a simple friendly, both teams put their best into the field and we all know that barcelona is always a candidate for the title and losing against barcelona has always been painful, something very bad. not to mention that it was not a game in which they were competitive on both sides, the result is obvious: real madrid was humiliated, conceding 3 goals and not being able to score at least 1 goal is something humiliating
Madrid have to do now is quite clear, as they have to clean up again to plan well what to do in the season that will start in a few days.
In this match, Madrid's defense after several substitutions was very weak which resulted in conceding 2 goals in the last 10 minutes.
On the other hand, it's also a matter of prestige, but as a point of reference it's not a sure thing as they can still improve in the short time they have left.
Hopefully, there will be a change of scheme as the current formation doesn't seem to suit Madrid too well.
Therefore, at this time they have to find another alternative because basically with the 2 striker scheme the fact is still a little complicated.
I don't really understand why Ancelotti used 4-1-2-1-2 in some of their friendlies because if you look at Madrid's playing history I think it would be better if Madrid tried the standard formation in 4-3-3 because it can still be used.
Jude can still be flexible as an attacking midfielder. Second strikers are good too but when their target man is struggling it's clear the 4-1-2-1-2 formation won't work well.
On the other hand, it is still not too late if you want a new striker if you feel Joselu is still unsatisfactory because there is still at least 1 month left until the player transfer is closed.
It was a friendly match and it's only natural for the coach to experiment with his strategy. In official competitions, they need a backup strategy including the formation they will apply later. And don't forget that sometimes they get a bad situation with a player getting a red card for example, of course it will make the scenario on the field change, it must also be considered by the coach and including maybe they will do a scheme like that in a friendly match, making the player get a red card.
I remember when they were still managed by Jose Mourinho, I forget exactly when, but at that time the situation was 2 of their players, Sergio Ramos and Xabi Alonso were forced to make them receive a red card, it sounds very crazy, because of course every team does not want a player to receive a red card, but it really happened.
I mean scenarios like this have to be prepared for, including experimenting with formations.
As I said before, this is not just a friendly because in my opinion this can also be important data, especially the opponent faced is a rival, of course they are aware that if they lose today, the possibility of potential doubt through the season will be very pronounced.
For matches with other clubs like Manchester United and Juventus it might still be possible but against Barcelona it's clearly different.
