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. Former Liverpool star McManaman believes Jurgen Klopp 's men could struggle to advance from the group, particularity if it comes down to the last game. They were also thrashed 4-0 by Liverpool at Anfield in the previous round when the gulf between the sides seemed huge.
A crucial miss from Daniel Sturridge in the beginning of the game set the tone for the way that Liverpool would go on against Red Star as they looked weak in defence and abysmal in attack.
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.
"Pavkov scored two lovely goals, but all the boys played really well - now if only we could play like this every week", he said.
"I think that message by not picking your strongest team to start with would have an effect with some of the players who did start".
"I maybe lacked a bit of efficiency and a bit of luck sometimes, but you always need to keep working hard in training and keep the faith", the 32-year-old told BT Sport. "Last season everyone was used to us scoring four or five goals".
"We lost our mojo in the game, not in general". That can't be possible every single game. They were more effective than us.
"You can't give teams that start", Liverpool midfielder James Milner said. "It's no different if we win or lose but we'll definitely have a debrief and I'm sure a few things will be said". This is football. There are players waiting for their chance, and they have all my confidence as well'.
