Atletico Madrid suffered a tough defeat against Arsenal in the Champions League. Simeone's team conceded four goals in just thirteen minutes and suffered their second defeat in the top continental competition. The visit to England is becoming a headache for Atletico Madrid. Simeone's team fell apart in the second half against a rival that scored four goals in a brief span of 13 minutes. A real shock for Simeone's team, which was almost always at the mercy of the gunners. Arsenal took advantage of the emphasis of their fans to continue gaining confidence. Constantly the ball was in the field of the Madrid team, and at the quarter hour mark Lewis-Skelly was close to opening the scoring. The left-back slipped into the area and executed a shot that was too crossed and went just wide of the left post defended by Oblak. Meanwhile, Simeone's team clung to the counterattacks to take some oxygen. Saka had a clear one-on-one against Oblak, but at the midpoint of the first half Atleti began to show signs of life. Raya trusted himself to protect the ball and Giuliano almost stole the wallet. In the immediate throw-in and with Raya out of his goal, Simeone gave way to Julián Álvarez who, seeing the empty goal, tried to surprise, but the ball went just wide. The Atleti was not dead, and that's because Arsenal had a goal disallowed for offside by Martinelli for a clear offside. The bleeding began in the second half, when Arsenal scored four goals in a brief span of 13 minutes. Own mistakes and details of quality from the gunners led to an inevitable outcome, although perhaps the punishment was excessive. Julián Álvarez, always differential, could have changed the course of events if he had adjusted his aim a few millimeters more. The Argentine found the crossbar with a shot from outside the area, but the ball went just wide. Atletico Madrid has a lot of margin still to rectify the situation, but in their second confrontation with a 'coco' they could not avoid their second puncture. The defeat is a setback for Simeone's team, which seeks to regain confidence in the next matchday. Atletico Madrid must analyze their mistakes and work to improve their defense, which has been their Achilles' heel this season. With the defeat, Atletico Madrid stays with 3 points in the Champions League standings, while Arsenal tops the table with 9 points. Atletico Madrid's next game will be against Porto, in a match that promises to be very disputed. Simeone's team must be ready to face the challenge and seek the three points that bring them closer to qualification for the next round.
