Nasri was in the Arsenal side beaten by Birmingham in the 2011 final and remembers how the Gunners subsequently collapsed in the title race.
The 26-year-old said: "I have the experience of losing the Carling Cup with Arsenal.
"After that we only won two games in the league, so a win would be really important for us and the confidence.
"I hope it is going to be the same kind of game."
