Cahill was delighted with the atmosphere inside Goodison as the Blues staged their comeback, and was glad to have played his part.
He said: "It was unbelievable. You could see the game just needed a bit of spice and the manager put Beckford on, who chased after everything, and Victor was exceptional. The lads gave their all and then I went on to play off De Jong and try and win some challenges and change the game and that's what happened.
"Silva was brilliant for them, but the big thing was the pace of the game was so mellow. Everything in the first half was so smooth and some of the games I've played against Man City at their place, you have to get in their face and really unsettle and challenge them. The gaffer changed the game well and made some great results.
"The record against them is great and that's what we're capable of.
"We all reacted to the lads tackling and putting their feet in, and I just wanted to lift the spirit. You could see a bit of fear in their eyes in the second half and once you sensed that we went for the kill."
