And Toure, although conceding retaining their Premier League crown remains the priority, hopes Roberto Mancini's men can give a better account of themselves in this year’s European competition.
Toure told Sky Sports News: "I believe we can do it again and we have to go higher. The priority is the Premier League and go as far as possible in the Champions League.
"It is important we continue to improve and we hope we can be successful this year as it is an exciting year for us and for the fans.
"I have been here two years now and won two cups and now we need more and if we sign players this summer I hope they will be fantastic players."
His claims were supported by Argentine team-mate Zabaleta. The 27-year-old acknowledged the squad underachieved last season in Europe but underlined the desire to improve this time around.
"Every competition is important for us, our target is to try and win trophies this season," claimed Zabaleta.
"We have the Champions League. We didn't play our best in the Champions League, we know that, and maybe this year we will try and improve that work.
"We had a tough group last year, but I think we have good players to do better in the Champions League."
