Atletico Madrid's defense was too fragile when Barcelona pressed from all sides, but unfortunately Ferran Torres missed his two big chances. Pedri, Cubarsi, Inigo took advantage of goal opportunities well and that made Barcelona close the first half with a win. In the second half I think Atletico Madrid will make some adjustments in defense, Barcelona will also do it without having to reduce the intensity of attack. Yamal, Kounde and Pedri were really good in this game, but Raphinha and Ferran probably won't complete the game full time.
If Barcelona can play as well in the second half, then I think Atletico Madrid will have to accept defeat in this first leg with a record of conceding more than 4 goals. However, Barcelona must also remain focused on defense rather than total attack. Atletico Madrid is dangerous in building fast counter attacks, so Hansi Flick also still has to instruct his defenders not to get too far from his defensive area.
If any team can make 2 goals under 6 minutes and allow to be draw under a half, that team doesn't deserve that goals. I will say Barcelona was negligent with their defense and didn't know how to react to the stress of Atletico else there no way they will have the capacity to score 3 goals and allow Atletico to embarrass to them with 6 minutes goa, it should have been one so thag everyone will know it was a mistake but it was two goals but better they didn't sleep.
I am looking forward to atleast 2 more goals in fairness play in this second half. Atletico defense is very bad through out the first half. I'm not sure if they are going to patch it up in the second half but even if they do better and show some interest, I think they will collect more goals from Barcelona which is that 2 but if they don't show defensive mechanism, they will eat more goals than we are even discussing because Barcelona seems to be angry with that embarrassment of early concedes.
