Kenny Dalglish insists Liverpool remain a work in progress after his team came from behind to book a place in the FA Cup final by beating their Merseyside rivals.

Nikica Jelavic gave Everton the lead after a Jamie Carragher mistake. However, an equally disastrous blunder from Sylvain Distin gifted Luis Suarez an equaliser and Andy Carroll rammed home the winner three minutes from time.

Liverpool are now one game from adding the FA Cup to the Carling Cup but Dalglish was refusing to get carried away. "It is called a work in progress," he said. "We have said that many times before and there is no need for us to change. After the Carling Cup I said we are not the finished article and we are saying the same thing now."

Dalglish's side have gone through tough times in the league, with director of football Damien Comolli paying the price on Thursday, but the season would surely still be regarded as a success if Liverpool ended it as a double trophy winner.

"Winning gives you a good feeling," Dalglish said. "If you can't enjoy winning, you might as well put the lid on the box because it is time up.

"Whether [winning silverware] helps or hinders lies with the individual. You can get a taste of it, think it is great for us to go forward and try to win something else because you enjoyed that so much, or you can go complacent and say that's great we have won a trophy, that's all I wanted to do.

"The most important thing is that the players want to be more successful than they have been."

Everton manager David Moyes, who had gone into the match with high hopes, felt Distin's error was its turning point but had words of sympathy for his player, who apologised to fans afterwards.

Moyes said: "Sylvain is really down. He has been here a couple of times before and won the FA Cup with Portsmouth. He knows exactly what it means and how important it is and he has been great for us so far.

"I thought with the way we had been playing this was our chance. Liverpool have not been where they would like to be and we had been playing well. That is why the game was very even and there was very little between the teams." Jay Spearing fired an early Liverpool chance over the bar, while Everton had two off-target free-kicks from Leighton Baines and Jelavic, who also had an overhead kick saved by Brad Jones.

The opening goal arrived in 24 minutes when Carragher and stand-in left-back Daniel Agger hesitated when the ball dropped in the penalty area. When the vice-captain eventually decided to deal with it, he succeeded only in driving it at Tim Cahill.

The rebound fell to Jelavic, who coolly slotted a shot between the legs of a diving Jones, sparking wild celebrations from Moyes.

Carroll had a glaring miss at the start of the second half, heading wide from Stewart Downing's inviting cross to the far post, but Suarez made no mistake when Distin badly mis-hit a backpass, racing into the area to slide a low shot with the outside of his right foot past Tim Howard.

Carroll shot wide from a good position in the 78th minute and Jelavic drilled a shot into the side-netting. But the match was settled when Craig Bellamy, on for Downing, whipped in a free-kick and Carroll, who also scored the winner against Blackburn in midweek, at last found the target here as he flicked in a header.

There was time for substitute Maxi Rodriguez to hit the post from close range as Liverpool booked a third appearance at Wembley in three months and kept their season alive. For Everton, the priority will be to finish ahead of local rivals in the Premier League, something they have done only once before.
