Manchester City midfielder Samir Nasri labelled his role in Sunday's 4-1 thrashing of Manchester United as 'a little revenge' for the same fixture last year.
Nasri played a key part in City's opener as well as scoring the fourth goal as the Sky Blues ran riot over their neighbours at the Etihad.
It represented quite a turnaround for the French international from last December's home derby when Nasri ducked away from Robin van Persie's late free kick deflecting it into the bottom corner to hand United a 3-2 win.
In that instance the 26-year-old took the blame for handing the Red Devils the win, with then manager Roberto Mancini complaining that his side had only 'two-and-a-half men' in their wall.
And Nasri admitted his delight at the change in fortunes.
"It's a different feeling from last year, and a different feeling for me as well," said Nasri.
"Last year I was involved in the third goal in a bad way, so this was a little revenge. I just want to share this moment with our fans.
"Last year was a little bit sad because we were losing 2-0 and came back, but in the last minute Robin scored that free-kick.
"This year it was not the same scenario, and we are very happy."
The former Arsenal man also believes that the emphatic nature of the win sends out a message to the other teams in the Premier League that City are genuine title contenders.
"We have sent a message to our rivals that this year we can be a force. To win like that is always special," he added.
"We showed what good players we have in our team because we put in a very good performance."
"It was important to win this game, for ourselves as well as for the fans, because Arsenal won as well, and moved to 12 points."
