Jurgen Klopp's side now sit top of Group C on six points after thrashing Red Star Belgrade 4-0 in the reverse fixture at Anfield last month but the Reds boss knows it will be a much tougher task this evening in front of the hostile Marakana crowd. Their passing was sloppy, their midfield was ill-disciplined and they seemed to lack any sort of clear game plan.
Liverpool's options in reserve were supposed to ensure a stronger challenge both in domestic and European competition this season.
'We will keep going and playing because it doesn't take much for those chances to go in'. In the end you have to score goals in a game and if you think about how often we were in the box and around, that's what you have to do in a game but you have to make the last decision in the right way and we didn't. Maybe it's not been as good to look at but we've been effective at it.
"I don't say it is already serious if you lose twice but we have to make sure it will not happen again as the next game is an away game (against PSG) before a very hard home game against Napoli", he said.
"I think it made sense to make a few changes, a few we had to make and a few we wanted to".
Instead, it was Pavkov who impressed in front of goal, leaping highest at a corner to head in a right-wing delivery from Marko Marin and put Red Star ahead. That can't be possible every single game.
'Defensively Awful': Mourinho Relieved After Man United Fightback
Burley says that is a good trait for a team to have but is still yet to be convinced by Jose Mourinho's side. And Rashford pinpointed the same deficiencies, adding: "We have to improve on starting the games".
Maybe we are missing a bit of a spark in terms of not winning 4-0 or 5-0.
A run of bad results in Europe and less convincing performances in the Premier League has led many fans to believe that the departure of Jürgen Klopp's assistant Željko Buvač could be the leading cause behind the drop in form.
"We gave the ball away and that's not cool in a game like this, an atmosphere like this, a situation like this".
And Klopp has warned his squad that they can not afford to let slip any more points if they want to make it through to the last 16. "Shaq is our player, we love him, and he will play for us a lot of times, but not on Tuesday". "We're still confident we'll get through but we need to prove that now".
"The lads are disappointed".
"You don't forget about these results quickly", Robertson said.
"As players we've got to take take full responsibility and make sure it doesn't happen again", he told LFCTV.
