Manchester City legend Sergio Aguero has not ruled out a return to football, despite being forced into retirement last year with heart problems.
The 33-year-old was emotionally forced to call time on his playing career last December, just months after joining Barcelona after he was diagnosed with a heart arrhythmia while playing for the Catalan side.
The striker had experienced pain in his chest and breathing difficulty during the first half of Barcelona's 1-1 home draw with Alaves on October 30.
The Argentine was taken to hospital for cardiological tests and was initially advised by medics to take a break from the sport.
