The 33-year-old midfielder said: "I think in the Premier League everything is possible. In football you have to be positive. I am a positive guy.
"I know it is tough sometimes but you have to accept that and continue to work hard, and we will have the chance. We just have to win a couple of games and everything will come back again.
"On Saturday we have an important game. We have to keep going. It is a difficult situation but what we have to do is work hard and try to bounce back.
"The league is still long. We have to try to do the business on Saturday and then we are coming back again."
Toure added: "When you see over the game it is difficult to take because we were more unlucky than lucky - all the rebounds, the ball always missing when coming back to you.
"But that is football, we have to understand that. It can happen. When you see all the game I don't think we played badly.
"If you look at the result, 4-0, it means we played badly - but we didn't play so badly. We were unlucky from my point of view."
Toure claims confidence in the dressing room will not be badly damaged.
Asked if the players were feeling low, he said: "Low? No. Of course nobody wants to lose this kind of game, and after the way we lost like that nobody wants to talk.
"But I don't think we lack spirit. The guys were there. Sometimes football is unfair. I think it was a consequence of bad luck, what came.
"We have to try to be positive for the next game and look forward."
