Liverpool were on the end of a surprise 2-0 defeat last night in Serbia, as Red Star Belgrade deservedly picked up their first win the Champions League since 1992. 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.
Markovic looked destined to leave Anfield in the summer and was close to finalising a permanent move to Anderlecht after spending the second half of last season on loan with the Belgian side and even travelled to Brussels on deadline to put the finishing touches to the deal.
Nevertheless, Milner was frustrated by Liverpool's failure in front of goal.
They arrived in Belgrade in first place in the group but has ceded the initiative and will be overtaken by either Napoli or Paris Saint-Germain, who meet in Naples later Tuesday.More news: India lauds US exemption on Iranian oil sanctions
A fee of £2.9 million had been agreed between the clubs but at the eleventh hour, Markovic had a change of heart and made a decision to return to Liverpool, where he is now in the final year of his contract.
"I think it's one of those periods we need to get through", added the Scotland captain.
"It's still in our hands: if we win our next two games we go through, but that was a great opportunity missed for us".

"We lost our mojo in the game, not in general". 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.
"You don't forget about these results quickly", Robertson said.
The Reds had their chances in Belgrade - most notably through Daniel Sturridge in the first half - and they hit the frame of the goal twice. "The gaffer, win or lose, always speaks more the day after because that's when he can clear his head and that's where he gets the best out of us".
"But I will have to sleep in the morning because we have an important game this weekend".More news: Smog Envelops Delhi 2 Days Before Diwali, Air Quality May Worsen
