Arsenal midfielder Jack Wilshere is targeting the Gunners' meeting with Manchester United in May as their way back into the Barclays Premier League title race.
The North Londoners are five points off the pace in the race for the title, after drawing with relegation threatened West Bromwich Albion, a result which allowed leaders Manchester United to extend their lead at the top.
Arsene Wenger's side still have a game in hand, against rivals Tottenham Hotspur, and host United at the beginning of May, a match that Wilshere says it a must win.
"There are nine games left and we really have to go to it," he said.
"United still have to come to the Emirates and we will have to beat them — from now, that is the biggest game we have to look forward to. Until then, we will just have to win every game.
"We all feel we are still their main challengers and we believe we can win it. Hopefully the fans do as well because we need them behind us."
United have already beaten Arsenal twice this season, the most recent of which came in the FA Cup quarterfinal where goals from Fabio and Wayne Rooney's helped book a semi-final date with neighbours Manchester City
After the international period, the Gunners face a potentially decisive run of match with games against the Lancashire duo Blackburn Rovers and Blackpool followed by the visit of Liverpool to The Emirates Stadium and that crucial game in hand against Spurs.
They host Sir Alex Ferguson's side on May 1st, in a game being build as a potential title decider with just three league games remaining after The Emirates Stadium showdown.
