Going down to the wire: Arsene Wenger believes his Arsenal have to win all of their remaining games this season if they are to lift the Premiership trophy
Chelsea manager Avram Grant also hopes his side can land a psychological advantage by playing the day before the leaders. The Blues, who travel to Manchester City tomorrow, could close the gap to two points by the time United kick off. Grant said: "We have come to an important part of the season and only Manchester United are ahead of us.
"This could be a chance to put pressure on them, and it is a chance we must take. We beat Arsenal to get into this position and will do everything we can now."
As the mind games between the three rivals escalated this afternoon, Ferguson used his pre-match briefing to warn Chelsea and Arsenal they cannot afford to drop any points this weekend or they will be out of the title race.
The Manchester United boss said: "The most important thing now is that we do our own job because we have come to the stage of the season where every game is as good as a League decider.
"Nerves are going to play a part and there will be shocks, but we just have stay consistent because the team that is most consistent will win the League."
Meanwhile, Barcelona playmaker Ronaldinho will be sidelined for six weeks with a thigh injury, ruling him out of a possible Champions League semi-final against United.
