What superiority are you talking about? This season, they only met 4 times, 2 times in Laliga, 1 time friendly match, and 1 time Spanish Super cup. They were defeated in the friendly and Spanish but won 1 Laliga and lost 1 and the basis of the problem was when Benzema became injured that period and there was no better option than can play that striker position than him
Even with Benzema, they still lost the El Classico but it is one of many things to discuss. Real Madrid fans have due diligent reasons to argue that they even had chance to win El Classico if VAR decision is not too strict against the goal of Marco Asensio.
I smell another problem in Real Madrid now. Vini Jr. gradually becomes more confident with his shots so that sometimes he wasted good opportunities for Real Madrid. Like in the El Classico, if Vini Jr. passes the ball to Benzema in some situation, Real Madrid would have greater opportunity.
and for this reason, to win unserious team was a difficult task for Real Madrid. Yesterday also doesn't show signs of unseriousness, they became relaxed thinking a draw might be better at almost the end of the match but that doesn't usually go well when there is much pressure from the opponent and that is the reason for their defeat to Barcelona.
More injuries from Benzema and his limited appearance for Real Madrid do affect their general performances with non big clubs. However it is not only from Benzema as we see before World Cup 2022, they did played well enough but after World Cup 2022, he started to lose more points and at higher frequency. I think it is more related to some other old players in their squad and not only Benzema.
