"At the moment everybody still questions us, even more after our defeat at [Manchester] City," Wenger told reporters. But I see the game at City the other way round, that we can have even more belief after the game at City.
"People are only keeping in their mind the big matches that we lose, but we have won some big games.
"What is at stake is if you want to win the Premier League, you want to win the big games at home. It is as simple as that."
Wenger has won a trio of Premier League titles since arriving in England in 1996, and claiming a fourth crown a decade after his third is top of his priorities this season.
"It is not [about nine seasons] without winning a trophy, it is without winning the Premier League," he added.
"If you win the [Capital One] Cup, it does not change anything. It is the Premier League that is the most important thing."
