The Toffees have scored 12 times in their last five matches, including four against Sunderland on Easter Monday all from different players.
"We are delighted with the current form, we are playing well and scoring goals," said Round. "Nikica has had a great impact for us. He looks a top quality striker and when we did give him a breather it was good to see Denis Stracqualursi lead the line so well.
During that run January signing Nikica Jelavic has scored four, Victor Anichebe two, with Magaye Gueye, Steven Pienaar, Leon Osman and Leighton Baines also on target.
By contrast, Liverpool have found the net seven times in their last five games.
"Goals are coming from everywhere. Victor has got a couple in the last two, the likes of Leon Osman scoring more - we can get goals from other places," Round added.
"We are always a threat on set-plays; Marouane Fellaini is always likely to get one and I think Tim Cahill is ready to start scoring again and that is a very pleasing aspect."
Everton's last trip to Wembley was in 2009 for their FA Cup final defeat to Chelsea - which was their first since 1995 - while Liverpool were there as recently as February when they beat Cardiff to lift the Carling Cup.
However, Round does not think that put the Toffees at a disadvantage.
He said: "We have a lot of players with a lot of experience - John Heitinga has played in a World Cup final - and we have players who have played in big games, big arenas and that stands you in good stead."
