The Gunners' recent form has been less than impressive, with Saturday's 1-1 draw against Middlesbrough at Emirates Stadium their fourth consecutive stalemate.
"Again we were chasing the game [on Saturday] after conceding a really silly goal," Toure told the club's official website. "It is always difficult for the team to come back and we are lucky that we scored a late goal again.
"Now we just need to keep going and win the big games. We are still in the title race and as long as we play like we did late on [against Middlesbrough] then in other games we might be more lucky.
"We will try to go to Chelsea and get some points. We know that we can go anywhere and win - we have shown that in Milan. We need to repeat that kind of performance next week and then we can beat Chelsea.
"We do not have a match now in the week, so we will rest and when we come back, we will be full of energy and can give everything. The most important thing is to be confident and play your game, stay strong in your mind and believe that until the end it is not finished.
"It is going to be an exciting finish to the Premier League. Whichever team is more confident and consistent is going to win the title.
"At the moment it is hard because we have dropped two points in every game. But when we get back to winning, we can carry that on until the end of the season."
