Atlético Tucumán lost 1-0 to Argentinos Juniors in La Paternal in the local tournament, affected by collective failures and lack of tactical responses during the match. The Tucumán team showed a low individual performance and key errors that prevented them from reversing the result. The defeat deepens the results crisis of the Decano, forcing the technical staff to make urgent adjustments to improve the collective performance in the season. Luis Ingolotti showed firmness in several interventions, but came out without criteria in Molina's goal and that error ended up being decisive for the Decano. Maximiliano Villa suffered in the one-on-one with Jainikoski and was on the limit with a hard entry that could have conditioned the team. Clever Ferreira was correct at times, especially in the aerial game during the first half, when he cleared several dangerous centers. And Gastón Suso was acceptable in the first half, but declined in the second half along with the rest of the last line. The injury of Renzo Tesuri in the first half also affected the team. Javier Domínguez entered due to Ortiz's injury in the previous match, but did not manage to order the midfield or change the team's rhythm. Leonel Vega showed a lot of sacrifice and dedication in the mark, but never gave up trying. Franco Nicola was very discreet and did not influence the attack or manage to connect with his teammates. Nicolás Laméndola had a dangerous action at the beginning, but lacked continuity. Leandro Díaz was well controlled by the centrals and did not generate dangerous situations. Ramiro Ruiz Rodríguez tried to give dynamics to the attack and was one of the few who looked for something different. Alexis Segovia showed attitude, but had little time and did not manage to influence. Ezequiel Ham entered in the final without weight in the game. Lautaro Godoy had a brief participation and far from the rival area. Lucas Román returned after a long time without playing, but could not influence the attack. So the defeat of Atlético Tucumán against Argentinos Juniors is a hard blow for the team. But the technical staff must make urgent adjustments to improve the collective performance in the season.
