The following season he played a major role as City won their first Premier League title - and his best season was in 2013/14 when he scored 24 goals in 49 games in all competitions as Manuel Pellegrini's side won the title and League Cup.
Manchester City's incredible season continued as Pep Guardiola's side set a new Premier League points record with a comfortable 3-1 victory over Brighton and Hove Albion.
City boss Guardiola said: "97 points, a lot of goals, a lot of wins - that's a outcome of the season we have done". We're going to try for 100 points and finish this nearly ideal season in the Premier League. It's good. Now it's one more game. To be alongside United in the 1990s or Liverpool in the 1980s you have to win more.
"People are talking about me doing something for this club, but we have to thank players like Joe Hart, Pablo Zabaleta, Joleon Lescott as well". Three in six years Premier Leagues, but in this moment just one, but we've done better than the others, we can not deny.
"To be the best we have to win more", he added.
Griezmann to Barcelona? It´s down to him, says Atletico Madrid president Cerezo
I'm sorry but I think we have to be cautious about players who don't play for us". We have to continue working on this aspect to reach the finals.
"But in terms of statistics and numbers, this season we were the best, and that's why we are so satisfied". Kolo Toure presented his brother with a framed shirt at the end of the game.
"He's not leaving because he'll always be part of it", Guardiola said. "I will be released, to go and assess my duty in a different club".
"He's got the talent, he's got the desire and I think he still has the energy", said Toure. "Thank you for being a wonderful teammate both in the dressing room and on the pitch".
At +78, City are nearly certain to beat the goal difference record of +71 set by Chelsea in that same 2009-10 season.
"It was something special, brilliant and incredible. I wish him well and hopefully he can stay in world football, if he desires, and maybe come back here or another place".
