It's really unexpected how Rayo Vallecano can win against Real Betis when Vallecano don't have any good results in their previous matches.
I thought Atletico Madrid could make things difficult for Barcelona, but I was wrong. In fact I think like you, because they concede the ball too easily and it looks weak like in your picture. It seems Madrid have to learn a lot from Barcelona so they can make Atletico like a docile cat. It seems that Jao Felix became Barcelona's differentiating actor, with his anger he worked hard to make Simeone feel guilty about letting go.
Atletico Madrid didn't play with their full squad, that's why they got conceded easily. I think it's because of they're tired because they spent a lot energy against Inter few days ago. Hopefully after this match, they have 2 weeks to relax and prepare for the upcoming match.
