Barcelona striker Sergio “Kun” Aguero announced on Wednesday that he would be retiring from football at the age of 33, after being recently diagnosed with a cardiac arrhythmia.

Aguero, 33, was recently diagnosed with a cardiac arrhythmia — an irregular heartbeat. The former Manchester City striker was taken to hospital after he suffered chest pain in Barcelona's 1-1 draw with Alaves in October. He was then ruled unavailable for selection.
