The Reds were 3-0 winners against the Citizens in the first leg of their Champions League quarter-final thanks to goals from Mohamed Salah, Alex Oxlade-Chamberlain and Roberto Firmino.
Liverpool FC made a shaky start in the return leg at The Etihad after Gabriel Jesus broke the deadlock in the second minute to offer Manchester City hope of a remarkable comeback at Eastlands.
However, the Reds managed to deny Manchester City a second goal, although Bernardo Silva hit the woodwork and Leroy Sane had a strike controversially ruled out for offside ahead of half-time.
Liverpool FC equalised in the second half through Salah after his 39th goal of the season before Firmino secured their place in the last-four draw with a precise finish past Ederson.
Former Manchester United defender Ferdinand was full of praise for Klopp given Liverpool FC’s incredible improvement throughout the 2017-18 season.
“A lot of credit has to go to Klopp. He improves players,” Ferdinand told BT Sport.
“Oxlade-Chamberlain comes and is reignited. Salah is a different player. Mane has been brilliant again this season. Robertson, the left back from Hull, has been producing on this stage.”
Liverpool FC signed Netherlands international Virgil van Dijk in a £75m deal from their Premier League rivals Southampton in the January transfer window.
