Reports in Spain claim Sergio Aguero is considering retiring from football following a diagnosis of cardiac arrhythmia, which is believed to be more complicated than first thought.

According to Catalunya Radio, as cited by the Daily Mail, the 33-year-old Barcelona forward’s tests results have not been promising after he left the pitch 41 minutes into his first start with chest pains last month.

Aguero had initially been told to rest for three months but it now appears the issue could be far more significant.

Catalunya Radio says the option of retiring has been put to Aguero. Their report says that his condition is complex and could be ‘incompatible’ with professional sport.

Aguero joined Barcelona on a free transfer last summer from Manchester City and was making his first start for his new club, in a LaLiga match against Alaves, when he started feeling chest pains.

The Argentinian walked off the pitch before spending the next two days in hospital.

Barcelona then announced that Aguero would rest for three months while “the effectiveness of treatment is evaluated”.
