Everyone is talking about Lionel Messi's exit from Barcelona and a possible move to Manchester City. Meanwhile, Sergio Kun Agüero, who would be Messi's teammate if the Barcelona superstar finally decides to join the Premier League side, posted a video on his Instagram account showing that he is back on the field after recovering from a successful knee surgery.

Agüero, a Manchester City living legend, suffered a knee injury and underwent surgery in June. Although City manager Pep Guardiola waited until the last minute for Agüero, the Argentine striker missed the Champions League matchup against Real Madrid and the team's defeat against Lyon.

In the last couple of days, Agüero has been in everyone's sights as a friend and possible future partner of Messi at Manchester City. He even was forced to mure the words 'Messi', 'Leo' and 'Goat' during his last Twitch live stream, as people kept asking questions about the Barcelona's star future.

Kun Agüero Instagram's video: Back on the field

After more than two months of recovery, Agüero finally could return to the field. He posted a video on his Instagram account which shows the Manchester City striker during a training session. "Back on the field", he wrote.

Agüero is widely considered as one of the best strikers of his generation and one of the best players in Premier League history. He is the highest non-English scorer in the history of the Premier League and holds the record for most hat-tricks in the competition, with 12. Imagine what he could do alongside his friend Messi.
