Marouane Fellaini believes the identity of this season's FA Cup semi-final opponents makes for an even bigger tie than when the Blues contested the last four of the competition in 2009.
The Belgian was part of the Everton team who prevailed against Manchester United amid the drama of spot-kicks three years ago.
But with this year's semi-final throwing up a Merseyside derby, Fellaini feels the occasion will surpass that memorable day - for players and fans alike.
He told evertontv: "Next we have a very good game, a derby against Liverpool in the semi-final, and I hope we can win as that would be a great moment for us.
"I think there will be a fantastic atmosphere and it is a big, big game. I don't really have the words to describe just how huge it is.
"It is bigger than 2009 because it is a derby and I will work every day and do everything I can to help us beat Liverpool and get to the final."
Fellaini played a crucial role in the quarter-final defeat of Sunderland, snuffing out the threat of dangerman Stephane Sessegnon early on before pushing further forward and having a hand in both goals.
He added: "We played a very good game. We didn't let them have any chances. We had three or four chances and scored twice. It was great for players and the staff and also for our confidence."
If Fellaini picks up yellow cards in the next two Everton games he would incur a two match ban.
