Liverpool will face Manchester City in the FA Cup semi-finals at Wembley after beating Nottingham Forest at the City Ground.
Diogo Jota scored the game’s sole goal with 12 minutes remaining, nudging in Konstantinos Tsimikas’ left-wing cross.
Jurgen Klopp’s quadruple-chasing team dominated possession but had their job cut out for them by their tenacious Championship opponents.
Steve Cooper’s side had a late penalty claim denied by VAR after midfielder Ryan Yates was brought down by Liverpool goalkeeper Alisson.
The hosts also viewed Philip Zinckernagel’s miss as pivotal, the Danish winger side-footing wide from six yards following Brennan Johnson’s tempting cross just a few minutes before Jota’s goal.
While Forest having already defeated Arsenal and Leicester in this season’s competition, they found themselves significantly outclassed by Liverpool, despite Klopp’s seven alterations to his starting XI.
And, while they were energized by the electrifying atmosphere in what was the first FA Cup encounter between the clubs since the delayed 1989 semi-final following the Hillsborough disaster, they were put under enormous strain for lengthy stretches of the game.
Yates also had a late chance to equalize, but Liverpool, who created several wonderful chances of their own, moved to the last four rightfully.
