Liverpool needed a last-minute winner from Roberto Firmino to beat Monterrey and seal a place in the Club World Cup final.
The Brazilian proved an inspired substitution from Jurgen Klopp having only come on five minutes earlier.
Naby Keita had opened the scoring before Rogelio Funes Mori - the twin of former Evertonian Ramiro - had levelled things up for the Mexican side.
However, it was arguably Mo Salah who deserved the most credit for the first goal, setting up the midfielder with a fantastic through ball.
It was inevitable that the Reds were tested given the number of injury problems they had ahead of the trip to Qatar.

Even though this was their strongest possible side Klopp still fielded something of a makeshift defence with Jordan Henderson at centre-back.
At least Liverpool could still rely on Trent Alexander-Arnold, the architect of Firmino's winner with a sublime ball.
The England international's vision really can't be overstated.
He'll have been pleased to know his exploits were followed by the watchful eye of Gareth Southgate as the Three Lions boss was in attendance.
After a ridiculous week of scheduling, there is little let-up for Liverpool as they now turn their attention to Saturday's final against Flamengo.News Now - Sport News
