The Reds advanced to the League Cup final after overcoming Stoke in a dramatic penalty shootout.
Jurgen Klopp’s men headed into the tie 1-0 up on aggregate following their slender win at the Britannia Stadium, yet they were pushed all the way as Stoke forward Marko Arnautovic levelled up the tie with the only goal of the game.
On the face of it the hosts can be quite fortunate to have made it through, having disappointed for most of the night with a number of players well below their best.
Among those was midfielder Jordan Henderson, with Waddle cursing his lack of authority on the game as he co-commentated for BBC Radio Five Live.
He said: “I think Henderson has had a poor game. A couple of seasons ago people were talking about him when he was instrumental in the midfield - now he seems to get on the ball from the back. He's not Steven Gerrard, let's put it that way."
While the comparisons with Kop hero Steven Gerrard is arguably unfair, Henderson is the Liverpool skipper nowadays yet he was far too passive against Stoke.
The England international dropped deeper and deeper, lacked any penetrating runs from midfield and was wasteful in possession – making a number of wayward passes and slowing the tempo.
Henderson was ultimately replaced by Christian Benteke on the hour mark, and the change helped Liverpool regain a bit of control somewhat after they were put under heavy pressure.
Simon Mignolet was the overall hero for the hosts, yet his two superb penalty saves in the shootout masked over a poor team display with some alarming individual performances.
