The only goal of Kun Agüero with Barça was the last of his career.

It was the first Classic after the pandemic and it didnt sit well with Barça: Real Madrid took the victory at Camp Nou on October 24, 2021, that is, just four years and a month ago. The goal for Barça was scored by Kun Agüero but it came very late, already in stoppage time and with the score 0-2 for a few minutes, after the goals from Alaba –in the first half– and Lucas Vázquez.
