The Citizens are preparing to welcome PSG on Tuesday night, with one key player set to be missing from the squad.
The 28-year-old Frenchman has only recently made his return to first-team football and Nasri told Sky Sports he understands the decision made by the manager, because he wasn't expected back so soon:
"It was something I was really okay with. When I had surgery the target was to maybe play one game before the end of the season."
Nasri's exclusion from the squad allowed young Nigerian starlet Kelechi Iheanacho to be part of City's European adventure and, although he accepts the fact he has been left out, he admits he will be a frustrated on-looker on Tuesday night when Paris Saint-Germain come to the Etihad:
"The only thing is it is PSG and I am from Marseille. That is like United against us. But that is just about it. I am going to be with the team and try to help them."
Nasri scored in City's 2-1 win over West Bromwich Albion on Saturday and he looked to be in fine fettle after spending so long on the sidelines. It is a blow for City not to have him involved and a decision that Pellegrini would surely reverse given the chance.
