The Argentina international has confirmed the knock to his knee is not as bad as first feared having been stretchered off against Southampton in their 3-2 win on the opening day
The 24-year-old was hugely influential in his debut season in England, scoring 23 goals in 34 league games, including a memorable last-minute winner against QPR on the final day of the season which secured the title for his side.
Worryingly for City their star striker appeared set for a lengthy spell on the sidelines after being stretchered off inside the opening 10 minutes of their season opener after a strong challenge by Saints full-back Nathaniel Clyne.
However, Aguero dispelled such fears, and has confirmed his condition has improved and he is ready to begin his recovery.
"Thank you all for your concern. I'm better but still resting with an ice pack on the swollen area," Aguero said via Twitter.
"And very eager to start recovery physio tomorrow! I'll keep you posted. All the best!"
