Samir Nasri is convinced this season is Arsenal's best chance of winning the league.
Nasri is relying on Liverpool doing Arsenal a massive favour by beating United at Anfield tomorrow.
He insisted: "We can feel the Premier League title at Arsenal this season. This is our time to win a trophy. It would be a huge blow to finish with nothing.
"Chelsea are not as good as they were last year and neither are Manchester United. So it feels like it is now or never for Arsenal.
"Two years ago, United were untouchable with Ronaldo and Rooney scoring every week but this year they have been unconvincing, especially away from home.
"Chelsea were very consistent last year but this season they just fell down after eight games.
"Now if we can beat Sunderland we will close the gap to just one point behind United, who must play at Liverpool on Sunday without Ferdinand and Vidic.
"United's strength this season has been their defence and, without those two, anything could happen at Anfield because Liverpool and United hate each other."
