The Gunners boss believes picking a consistent side has helped his side find their form.
The French tactician has selected the same side for the last six Premier League games, the first time the Gunners have done so in 21 years - when George Graham was in charge back in January 1994.
And Wenger believes that a consist selection policy, and the cohesion it has brought about, is key to the form his side have enjoyed during 2015, in which they have been the league’s top-performing team.
“We had positive games and positive results, and there is no need to change,” he said.
“I believe we have a stability at the moment that brings us as well good cohesion in the team. That is vital when you go into the final part of the season. I always change players, and I can change one or two but never six or seven.”
The Gunners take on Sunderland on Wednesday in their penultimate game of the season, before taking on West Bromwich Albion at the Emirates on the final weekend.
They currently trail second-placed Manchester City by five points and are aiming to finish above their rivals, but are also having to hold off the challenge of Manchester United for third place as well.
Once the season is over, they have an FA Cup final against Aston Villa to contest also, with Wenger saying it is important that they go into that game with a winning mentality and the confidence level to boot.
“It is very important for us to go into the FA Cup with a winning mode and good confidence level,” he added.
“We have the possibility of taking six points but it will not be enough if Manchester City win their last game against Southampton. That is likely. How much chance do we have? I don’t know. The only chance we have is to win our games.”
