The Ivorian is urging his Manchester City team-mates to put in maximum effort when they face last season's FA Cup and Champions League winners in Sunday's Wembley semi-final
The reigning Premier League champions are in imminent danger of seeing United claim their title, but are hoping to rescue their season by winning the FA Cup - and Toure has underlined their determination to beat Chelsea in Sunday's semi-final.
The midfielder has admitted that the game against Rafael Benitez's side will be difficult, but believes Manchester City have enough quality to overcome the Blues.
"All we can do is do everything in our power to win the game both individually and as a team," Toure told the official Manchester City website.
"We have a really tough challenge because Chelsea are a very good team and they have some fantastic players and to beat them we will have to be at our very best.
"We were faced with a similar challenge against Manchester United in 2011 and it was because we fought so hard and played really well that we beat them – the same is required on Sunday and we can't leave the pitch with any regrets.
"I'm very focused on what we have to do and the whole team is and if we win, we will have done so because we deserve it.
"Wembley is a very special place for me and I have some great memories from our last FA Cup run, particularly the semi-final and final for obvious reasons so I hope I can experience more great moments this season."
