Moreover, Barcelona's performance this season has been less stable compared to Atletico, but now everything has changed and the additional 3 points have put Barcelona in second place in the standings. I think Atletico must know that all teams are the same and must try to win and not just focus too much on their local rivals like Real Madrid. The additional 3 points are important to maintain stability and also create a safe position in top competition. 
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. Atlético Madrid were favorites in this match. This team is very strong in home matches. It was Atlético Madrid's first defeat at home in La Liga. Also in the Champions League, Atletico Madrid won the home match against the powerful Inter Milan with a great performance. Therefore, the Atletico Madrid team was considered as the favorite in this match as well.
However, even though it was a home match, we did not see a good performance from Atletico Madrid. Barcelona players performed very well in this match. Barcelona's performance was set in this match. And the entire match was dominated by the Barcelona players. Atlético Madrid's players could not create any strong attacking opportunities.
