Alisson labelled Liverpool's incredible Champions League comeback a "dream" after contributing to Barcelona's capitulation for the second time in just over a year.
Liverpool reached back-to-back Champions League finals in sensational fashion, stunning Barca 4-0 at Anfield on Tuesday to overturn a 3-0 first-leg deficit.
It was another forgettable European night for Barca, which was remarkably eliminated by Roma in last season's quarter-finals after surrendering a 4-1 lead following the opening leg.
Alisson was part of the Roma side that shocked Barca 3-0 in the return fixture to advance on away goals in April 2018 and the Brazil international – now preparing for a European decider with the Reds – revelled in Liverpool's achievement.
"It's an incredible feeling indeed, wow what a game and what an effort," Alisson told Sky Sport Italia. "It had already happened to me as my Roma knocked out Barcelona last year.
"I am happy when I can help my team-mates out like this… It's amazing, it's a dream. We now have one objective, to win the Champions League final.
"We worked hard this year and we were ready to face Barcelona tonight. In the first leg, Barcelona missed a huge chance late on as they could've made it 4-0. At 4-0, it would've been very hard for us to comeback but at 3-0 we still believed.
"We made a huge comeback and our fans were behind us all game long. It was a memorable night indeed."
Liverpool will face either Ajax or Tottenham in the Champions League final in Madrid on June 1.
