Goalkeeper Joe Hart is keen for his Manchester City side to gain revenge on tomorrow's opponents Chelsea.
City's first loss of the season came against the Blues back in December, with Frank Lampard scoring the winner after Gael Clichy had been handed his marching orders.
With just ten matches of the season remaining, Hart is aware how vital a victory will be to City's title hopes.
"One result can literally change everything. It's madness but it's great. Being four points behind won't have any bearing on how we play," told The Sun. "We owe them one. They were the first team to beat us in the league this season.
"We didn't feel we were outplayed but we lost Gael Clichy to a red card, we could have had a penalty ... there's a lot of could-haves and should-haves.
"But we lost the game and now we need to beat them."
City head into the match four points behind leaders and rivals Manchester United.
