Despite recent poor form in the league, Dalglish was delighted with his side and was quick to praise their team spirit.
"I think the players that were out there - and the players that have made a contribution throughout the whole run in the FA Cup - have been fantastic for the football club," said Dalglish.
"Their attitude, application and intent in getting that positive result from today's game was there for everybody to see.
"Whether it's deserved or not, people are going to have their own opinion on it - but everything needed to win a football game, we showed today as a team."
Liverpool will play either Tottenham Hotspur or Chelsea in the FA Cup final, which will take place on May 5.
