Manchester City lost 1-0 to the Blues in the Premier League 12 days prior to Saturday's FA Cup revenge victory, when goals either side of the break from Stevan Jovetic and Samir Nasri comfortably secured progression to the Quarter-Final.
And Manchester City skipper Kompany feels the biggest difference on this occasion was his side's willingness to adapt and improve tactically, as they produced a far superior performance than in their Premier League meeting with Chelsea.
'Twelve days ago, we had a really bad game. We gave them a lot of chances', the 27-year-old told ITV Sport. 'But we created a lot so today we just adapted and they played the same.
'We wanted revenge today. From the word go, we were spot on, creating a lot of chances and not giving any away. We knew they were strong on the break so we controlled that.
'It was a big one against a strong team. We love this competition, we love the FA Cup. It was a great game for the competition and we are happy with the result'.
The draw for the last eight of the world's most famous domestic Cup takes places on Sunday afternoon, with Manchester City one of three sides already in the hat.
Manchester City are joined by the team that beat them in last year's final - Wigan Athletic - and Sunderland, the side they are due to face in the Capital One Cup Final in early March.
Will Manchester City reach their third FA Cup final in four years ?
