Klopp regularly conducts analysis with his players the day after a game, having reviewed the match himself at least twice but Wednesday's debrief assumed a more critical air given the nature of defeat and the precariousness of Liverpool's position in the group.
Brazilian International goalkeeper Alisson Becker joined the Anfield club in the summer for £56m from Roma, and Teamtalk have reported that the former Liverpool stars Steve McManaman and Michael Owen felt the stopper was particularly at fault for the second goal in the game.
Failure to beat PSG in Paris would set up a tense must-win finale which could also entail needing a win by two clear goals to redress their head-to-head record against the Serie A side.
A fee of £2.9 million had been agreed between the clubs but at the eleventh hour, Markovic had a change of heart and chose to return to Liverpool, where he is now in the final year of his contract. "Last season everyone was used to us scoring four or five goals".
Jos3 (@Joe_kop) in his reaction after the game said that: "Lallana is pure garbage". That can't be possible every single game.
"In all areas, we didn't start and when you don't start well in the Champions League you can get punished". Maybe we are missing a bit of a spark in terms of not winning four- or five-nil in most games but if he [Klopp] thinks that then we need to try to get it back.
Many expected Morata to feature again on Thursday after his recent good form, with Sarri suggesting that the striker needed to work on his mental fragility following his side's win over Crystal Palace.
"You don't forget about these results quickly", Robertson said. We can't be letting teams get a start.
Zola acknowledged the duo have not always been at their best this campaign, but insists they are just taking their time to adapt to Sarri's demands. "I didn't like the first half because we moved the ball only slowly", Sarri told reporters.
