Raheem Sterling has signed a contract extension with Manchester City to remain at the club until 2023.
Sky Sports News reported on November 1 that Sterling's representatives had reached a verbal agreement with City over a new deal.
Sterling's original contract was due to expire in 18 months, but he has now committed his long-term future to the Premier League champions.
Sterling told City's website: "I'm delighted to sign. My development here has been incredible. I felt from the minute I got here it was the right choice for me. It's really paid off for me and I'm really grateful.
"Every season you come in you want to do better than your previous season. You want to try and develop and get better.
"With the facilities we've got here there's no reason not to. With the coaching staff and the players we have in this team it's the perfect environment to develop and get better."
The England international has registered seven goals and five assists this season.
Sterling joined City from Liverpool in 2015 in a deal worth up to £49m and has since scored 48 goals in 151 appearances for the club.
The 23-year-old enjoyed the most prolific campaign of his career last season, scoring 23 goals in all competitions as City won the Premier League title with a record 100 points.
Ciy's director of football Txiki Begiristain said: "This is a significant moment for the Club. Raheem has improved dramatically in the past two seasons and is now one of the Premier League's best attacking players.
"His statistics tell their own story. He's quick, strong and excellent in front of goal - everything a modern-day forward needs to excel. We're all delighted he has committed his future to City."
