Díaz, who has been instrumental for Liverpool this season, received the ball in a dangerous position within the Girona box. As he prepared to shoot, a Girona defender appeared to make contact with Díaz's planted left foot, causing him to lose his balance. The Colombian forward tumbled to the ground, appealing for a penalty.

Although the referee initially waved play on, the VAR intervened, advising the official to review the incident on the pitchside monitor. After a lengthy check, a penalty was awarded, much to the dismay of the Girona players and coaching staff. Salah stepped up to take the spot-kick and calmly converted, securing all three points for Liverpool.

The decision to award a penalty sparked considerable debate, with many pundits and fans arguing that the contact between Díaz and the Girona defender was insufficient to warrant a spot-kick. However, the referee's decision stood, and Liverpool were able to extend their unbeaten run in the Champions League.

With this victory, Liverpool finished top of their group and secured their place in the knockout stages. The Reds have been in imperious form in Europe this season, winning all six of their group stage matches and conceding just one goal.
