Nasri's entire tenure at Manchester City has resembled a firework that never takes off.
Two summers ago, City spent a reported £25 million to take Nasri from rival Arsenal.
After the shift Nasri put in this season, City seem poised to take anything offered to close the book on the Frenchman's tenure at the Etihad.
Nasri has two Premier League goals this season. So does Ryan Giggs, which is amazing considering that Giggs is 106 years old.
When the manager wants to punch you and tells the media as much, there is little ambiguity about how he feels.
Considering Nasri's reported £150,000 per week in wages, though, Mancini was probably afraid of a "you break it, you bought it" sort of rule being enforced against him if he biffed the little Frenchman for his insouciance.
For his part, Nasri had already established his own concern for his delicate self, submitting one of the most shameful punk-outs in a defensive wall ever seen.
That it happened on his home pitch against Manchester United, with the league results still very much in doubt, probably makes that moment his legacy at the Etihad.
