The former Toon No.9 headed a dramatic late winner against Everton after missing a string of chances earlier in the game.
As we all know, he put in a transfer request 14 months ago to pave his way to a future on Merseyside.
Carroll told Liverpoolfc.tv: "It's a great feeling scoring a goal at any time but with it being at Wembley and against Everton, it's even better.
"That's why you come to Liverpool FC to play in games like this and you want to win things. Getting to Wembley twice is amazing.
"We have to dedicate this win to all the Hillsborough families.
"It's a great feeling for us and the fans, and everyone involved at Liverpool FC.
"Going 1-0 down was disappointing but I thought we showed what we are all about in the second half.
"We kept at it and Luis got us level with a great finish and then Craig put a great ball in for me for the winner.
"I had a few chances and should have probably put a few away before I scored but I kept at it, kept working hard and got the goal."
