Roberto Firmino scored a dramatic stoppage-time winner, to give Liverpool victory over Mexican side Monterrey and book their place in the Club World Cup final.
Naby Keita opened the scoring for European champions Liverpool in the 12th minute, but Rogelio Funes Mori responded two minutes later, as Monterrey frustrated Juergen Klopp's side until Firmino flicked home at the death.
Liverpool will meet South American champions Flamengo of Brazil in the final. Flamengo beat Saudi Arabia's Al Hilal 3-1 in their semi-final.
"It was a tough game. We showed our quality in the last minute," Liverpool striker Mohamed Salah said.
Liverpool and Flamengo met in a 1981 version of this tournament when the Brazilians won the meeting of the European and South American champions 3-0.
In contrast to the recent world athletics championships in Doha, the Khalifa International Stadium was largely full for the FIFA event, with an attendance of 45,416 given for the second semi-final.
"I was afraid of extra time, I was more then happy that he scored the goal. He helped us a lot," Reds manager Klopp said.
"We controlled the game for a long period. I'm really overly happy with the performance because I knew it's going to be tough.
"It will be more difficult [against Flamengo] for sure."
Liverpool were without defender Virgil van Dijk due to illness while Sadio Mane and Firmino didn't start as Klopp rang the changes at the unbeaten Premier League leaders.
They had a bright start when Salah released Keita to score.
But Monterrey were level just two minutes later.
Goalkeeper Alisson Becker saved well from Jesus Gallardo but Funes Mori tapped home on the rebound.
Barovero then denied James Milner while Alsson denied the lively Dorlan Pabon on the half-hour mark and again in the 50th on a free-kick as the Concacaf champions defended well and tried to counter-attack.
Still, Keita got another chance in the 58th but his unmarked shot from some 12 metres wasn't easily saved.
Divock Origi then miscued on James Milner's pass shortly after Mane replaced Xherdan Shaquiri.
Firmino then came on in the 85th to grab the late winner at the near post, after Salah had kept the ball in play and Trent Alexander-Arnold crossed from the right.
