Manchester City legend Sergio Aguero has admitted he doesn’t know whether he’ll be able to run again due to his heart condition.
The former striker was forced to retire from football back in December after suffering from a heart arrhythmia while playing for Barcelona.
Aguero was making only his fifth appearance for the Catalan giants since making the move from City during the summer, but had to be substituted during their 1-1 draw with Alaves in October after complaining of chest pains and dizziness.
