It is instructive to note that the Argentine forward joined Barcelona on a free transfer after parting ways with Manchester City last summer, but he was sidelined due to an injury in the first stretch of the season and only made his debut against Valencia on October 17.

Aguero played just five games for the Blaugrana and managed to find the back of the net once, doing so in the Clasico against Real Madrid at the Camp Nou.

In total, he played 165 minutes for Barcelona in LaLiga Santander and Champions League before leaving the pitch against Alaves due to chest discomfort.

Medical exams showed that Aguero suffered an arrhythmia and although those around him have tried to play down scenarios regarding a potential retirement, the Argentine has decided to call it a day with his football career.
