Despite the valuable 2-1 win over Atletico Madrid, the match revealed some defensive errors that could pose a threat to Barcelona in upcoming Champions League encounters, according to the Spanish newspaper 'Mundo Deportivo'.

During the match, Atletico scored their first goal through Giuliano, and Frenchman Antoine Griezmann almost became a hero on two occasions, benefiting from repeated defensive errors similar to those that occurred in the heavy 4-0 defeat against Atletico in the first leg of the Copa del Rey semi-final.

In the first instance, while the score was 0-0, Atletico Madrid executed a cross to Baena who sent it parallel to the penalty area, where Griezmann was in a free position without marking, Koubarsi intercepted the pass, while Gerard Martin was far from his coverage, and Araujo, Eric Garcia, Pedri, and Cancelo were outside the penalty area, giving the attackers space to exploit and threaten Barcelona's goal.

The second instance, which ended with Giuliano scoring the first goal, was the result of a long pass from Lenglet that bypassed three defensive lines, leaving Griezmann deliberately offside for Giuliano to benefit from, who took advantage of the defensive confusion and faced the goal in a better position with almost no resistance.

These errors indicate a repetition of similar tactics to what happened in the first leg of the Copa del Rey semi-final, where Atletico relied on quick passes on the wings and parallel crosses to the area to create dangerous shooting opportunities. Barcelona must focus on these points in the upcoming Champions League first leg, then the return leg at the Metropolitano Stadium to ensure maintaining the lead and benefiting from previous victories.
