Klopp could barely sit as he watched his side play out a tense final Group C game on Tuesday night, with Mohamed Salah‘s goal proving the difference.
It could have been much more comfortable for the Reds, with Sadio Mane particularly wasteful as the hosts fired 13 of their 22 attempted shots off target, with five more blocked.
And Napoli came very close to scoring a devastating last-minute equaliser, but Alisson pounced off his line to cap a defensive display that Klopp described as “some of the best I ever saw.”
“I’m still full of adrenaline. This game was amazing, outstanding. The boys played with their whole hearts; each part of their body,” he told reporters.
“Our offensive pressing and defending was some of the best I ever saw.”
Liverpool could face the likes of Borussia Dortmund or Barcelona in the next stage of the competition, but Klopp did not want to speculate as to his ideal draw next Monday.
“I don’t care…we are second in the group [so] we will have an outstanding, strong opponent, that’s it,” he said.
“Trent has a knock, not sure exactly what it is. Milly has a cramp. We don’t know anything [yet],” he explained.
Hopefully there are no major issues, with Alexander-Arnold and Milner settled as first- and second-choice right-backs with Joe Gomez sidelined, and Matip partnering Virgil van Dijk in both of the games the Englishman has missed so far.
