The North London outfit are currently fourth in the table, seven points adrift of leaders Liverpool.
Despite Everton being just four points behind the Gunners with a game in hand, Wenger is confident that his side have "turned a corner" following last weekend's 1-1 draw with Manchester City.
"We know that every game becomes vital," Wenger said in Friday's press conference. "We came out with a strong performance against City and I think we have turned a corner.
"All the teams at the top are in danger everywhere, especially when you play teams who fight not to go down. We have a small percentage to win the title, but we have to give everything to make it possible."
Arsenal will take on Everton at Goodison Park this Sunday.
