Wenger believes that the team's good form this year is down to a more positive atmosphere inside the Emirates Stadium instead of the discontent that has been voiced during recent campaigns.
"There is certainly more support from the stands than this time last year," the Frenchman told the club's official website.
"It will be a massive advantage because when we have a difficult patch during a game, our fans feel it and support in response.
"Last year it was moaning when we had a weak period. You feel that. Of course it gives the players more belief and more desire."
Arsenal head into tonight's match having won 10 out of 13 games in the league this season.
