This is a look at the defender of the Order of Milos Degenec, who last night retained a clean list in the Champions League victory with 2-0.
Milan Pavkov escaped for hosts, as Liverpool lost the second match of the Champions League in the season.
Reds can still qualify for the unusual stages of the European competition with predictions against PSG and Napoli.
If Liverpool wins in the French capital, they will progress, regardless of their run on the side of Napoli's Serie A side.
If they decide against the PSG, they must win in Napoli in their last game in December – defeat in the PSG would mean that they must beat the Italian side with two goals at Merseyside.
Qualifications would be almost certain if Liverpool wins in Serbia, but this was not for Jurgen Klopp.
And Degenek showed the Liverpool defeat in Belgrade.
"We played well and managed to turn them off," Degenek said.
"Pavkov has achieved two beautiful goals, but all the boys played very well – now, if he could play so every week
"I think Liverpool has underestimated us and consequently paid this mistake.
"I was talking [James] Milner in the tunnel, and he told me that he never experienced anything like the noise coming from the tunnel above.
"I believe we can do this again against Napoli."
Liverpool boss Klopp admitted that his side was led by Serbian SuperLiga.
"We had a few moments, we had some options, the biggest in the last two minutes, and before that was not enough," Klopp said.
"We have to admit – Congratulations to Red Star, it was well deserved. They have three points, we have nothing.
"We were not surprised at the Red Star tactics. We controlled the game in Liverpool, tonight we are not.
"Tonight we made life too easy, that's the problem. They earned it for the passion they showed."
