Arsenal midfielder Samir Nasri insists the Gunners are now the favourites to take the Premier League title.
The Gunners sit just four points behind Manchester United ahead of what could turn out to be a crucial weekend in the title race.
United face a tough trip to Anfield on Sunday to take on Liverpool, with Arsenal inviting Sunderland to the Emirates.
Three points for Arsene Wenger's men would pile the pressure onto their bitter rivals, a team Nasri feels are not as good as in previous seasons.
"When we played them at Old Trafford they didn't play their normal way. They were scared," he said.
"They played with three defensive midfielders and they closed the game down.
"They know that we can beat them. So we have more chances in the Premier League - better than United because I'm convinced of our qualities.
"Now we can feel we can win the Premier League."
As the title run-in hots up, the French international points to the fixture list for both clubs as evidence Sir Alex Ferguson's men will not have things their own way.
"We have the best fixture list. Manchester United still have to play Liverpool, they have to play Chelsea again and they have to come to the Emirates to face us," he added.
"Last year at this time we were six or seven points behind Chelsea, who were so consistent.
"Now if we beat Sunderland we come back to within a point of United, who have to play Liverpool without Nemanja Vidic and Rio Ferdinand, who have been so strong for them in defence.
"So something can happen at Liverpool, because they hate each other!
"If we win our game in hand against Tottenham, we can be on top - and that's why I said we feel that we can win the title."
Despite failing to end their trophy-less run after a shock Carling Cup final defeat to Birmingham, Nasri believes that it is still Arsenal's turn to take the league title.
With the Red Devils so far failing to hit top form and Chelsea stuttering mid-season, the 23-year-old insists it is his team who are in the best shape.
He said: "This year Chelsea are not so strong, Manchester United as well - so it is our time.
"Man U are not like they were two years ago with Ronaldo and (Carlos) Tevez. For me they were untouchable.
"This year away from home they have drawn quite a few or lost and overall have been unconvincing. Chelsea as well, they just fell down after eight games.
"This year we have not had so many injuries and everyone has grown up. It is now or never.
"I don't mean if we don't do it this year we will never win the trophy, but it is our best chance since I came to a club three years ago."
