I personally underestimated Atletico Madrid in that match. I believed before the match started that Real Madrid would win. But the reality was beyond my expectations. Even the scoreline was very surprising. A 5-2 scoreline didn't look like Atletico Madrid facing one of the strongest teams in La Liga.
Atletico Madrid truly looked like a team that had already identified the weaknesses in Real Madrid's defense. And I'm sure Real Madrid are starting to experience a decline in defense again after Trent's injury. Yes, Alonso has a lot to learn from this result.
I can't even remember the last time Real Madrid conceded so many goals in a single match. Someone wrote yesterday that Real Madrid hadn't faced any strong teams this season and that the match against Atlеtico would be a test for them, and I can say that it looks like they failed that test. It was a good match for Atlеtico, but after a match like that, one wonders why they haven't played as well as yesterday before, dropping points against Mallorca, Alaves, and Elche.
