Robin van Persie says victory for Arsenal in the North London derby with Spurs is "vital" for the Gunners.
And the Arsenal captain has challenged his team-mates to "put the record straight" by beating Tottenham at Emirates Stadium on Sunday.
After the disappointment of the 4-0 defeat in Milan which all but ended their Champions League hopes and the FA Cup exit to Sunderland, the importance of producing a performance against their arch-rivals is not lost on Van Persie.
"What better way to set things straight again than to beat Spurs?" the Dutchman said.
"I would rather be playing them now than on any other day, and we know that a win is absolutely vital.
"I don't think anybody would deny that Spurs have a really good side - and they've added consistency this season.
"They are winning the tougher games and, as a result, have made that next step towards the top teams.
"Spurs have invested a lot of money over the past few years, and when you look at the figures it's reflected in their league position."
Van Persie added in the Arsenal's Official Matchday Programme: "They are above us for the first time in many years, but it is in our hands to change the way things are going, win the game and start moving closer to them.
"A draw will not be a good result for us [on Sunday], either in our bid to catch up with Spurs or in our efforts to fight off our other challengers for a Champions League place."
Arsenal and Tottenham have issued a joint statement warning fans any anti-social behaviour will not be tolerated on Sunday.
Spurs' former Arsenal striker Emmanuel Adebayor is the biggest concern - he was the target of abuse during the first meeting between the sides at White Hart Lane in October.
Gunners boss Arsene Wenger believes positive support from the Emirates Stadium faithful is "vital".
He said: "Arsenal versus Tottenham is a passionate game, so you expect that.
"It is only a passionate game if your fans stand behind you and give absolutely everything like the players will do."
