Cahill produced a man-of-the-match performance along with his goal and admitted but for the heroics of goalkeeper Simon Mignolet, the Toffees could have scored more.
"I suppose I was due a goal," he told evertonfc.com. "I was already in midair. As soon as [Nikica] Jelavic touched it, I had to adjust and it hit the back of the net. All season I've been trying to get myself in the right positions.
"But this cup means so much to me, and also to the fans. I really wanted more to go in and hopefully go on and win today."
