This is not about victory because in fact, seeing the match Real Madrid seemed to not have the strength to beat a weak team. There are many things that may need to be evaluated, especially for the defense line because I saw them so easily penetrated by opponents even though if you look at the attack pattern built by Leganes players, it is not that dangerous because there is no speed like some top club players. It was still quite lucky because Garcia managed to break into Leganes' goal in the added time so that Real Madrid managed to win the match.
I very much agree with you. And Real Madrid still needs a lot of improvement, especially in their back line which looks very fragile and has many gaps. In that match, Real Madrid almost couldn't win. Even though the difference in strength between Leganes and Real Madrid should be very large. But in this match we saw that Leganes' strength level could still match Real Madrid's strength.
And unlike Real Madrid, we see that Atletico Madrid can win easily and with a very big score, namely 5-0. I hope Real Madrid can improve their weaknesses before the UCL match.
