Aguero was forced to call time on his playing career due to heart arrhythmia, with the former Argentina international being diagnosed after suffering chest pains while playing for Barcelona.
The 33-year-old had only joined the Catalan giants during the summer, having become City’s all-time leading goal-scorer during his 10 years at the Etihad.
After just five appearances for Barca though, he announced his retirement during an emotional press conference at the Camp Nou, where he was joined by City manager Pep Guardiola.
“Retiring under these circumstances is difficult, but life comes first – I’ve known that from the start,” Aguero said last month.
The Argentine hasn’t been seen taking part in any activity since retiring from football, but this week he took to Instagram to show off his skills in a new sport.
Aguero posted a video of himself playing tennis with a friend on a clay court in South America, captioning the video ‘training’ as if to hint there might be more to come from the former City superstar.
The short video shows Aguero hitting a few shots from the baseline before moving up to the net to smash the ball back, with his playing partner seemingly hitting the ball out.
And Aguero’s demonstration of his tennis skills were given the nod of approval by his former United rival David de Gea, who replied “Nalbandian”, comparing the former striker to his fellow countryman and former Wimbledon finalist David Nalbandian.
Aguero might not quite emulate the former world number three, but it’s certainly good to see the City legend back up and running after his scare last year.
