It is reported that he is currently having a medical at the Etihad Stadium.
He will join Sergio Aguero, Gael Clichy and Stefan Savic as the summer additions to an already solid looking squad.
Nasri is a supreme talent and will undoubtedly have a major role to play at Manchester City...eventually.
At the moment, though, where does he fit in?
David Silva is the playmaker that is currently deployed by Roberto Mancini, and to be fair, he is far superior to Nasri and will not be dropped to the bench for the Frenchman.
Although Mancini has stated that he will play a more attacking brand of football this season, I doubt that means he will play two 'luxury' players such as Silva and Nasri.
But with the club qualifying for the Champions League for the first time this season, a more rounded squad will be essential.
So it could be he case of a squad rotation policy coming into effect at City pretty quickly this season.
With the additions of Nasri and Aguero, City now have an attacking menu of Aguero, Edin Dzeko, Mario Balotelli, Carlos Tevez, Silva, Adam Johnson and Nasri.
That is some final third. There aren't many, if any, better in the Premiership than that.
Only really Barcelona have a better forward line in the Europe.
All of the above are match-winners on any given day, so City now have the the strength and depth to challenge on all fronts.
Here are two formations that could accommodate Nasri this season:
GK: Joe Hart
RB:Micah Richards CB: Vincent Kompany CB: Joleon Lescott LB:Gael Clichy
CM:Gareth Barry CM: Yaya Toure CM Nigel De Jong
CF:David Silva CF:Edin Dzeko CF: Samir Nasri
This formation could work maybe away against some of the leagues better sides, where Nasri and Silva, who are both midfielders by trade, could work back and make a midfield five.
GK: Joe Hart
RB:Micah Richards CB Vincent Kompany CB: Joleon Lescott LB: Aleksander Kolarov
RM:David Silva CM:Nigel De Jong CM: Yaya Toure LM: Samir Nasri
CF: Edin Dzeko CF: Sergio Aguero
Very attacking line-up which could be used against some of the weaker sides within the Premiership. With Silva, Nasri and Agureo feeding off Dzeko.
All in all, Nasri was a solid signing by City. He is not quite the world beater we have come to expect, but one who can definitely make a big impact on the side this season.
