Liverpool's season endured it's most miserable night so far in Serbia.
The Reds lost 2-0 away at Red Star Belgrade, with Milan Pavkov scoring twice in the first-half.
Luckily for Jurgen Klopp's side, Napoli and Paris Saint-Germain drew 1-1 in Naples to soften the blow.
Liverpool are still in a decent position to quality from their Champions League group, but their performances will need to drastically improve.
If they play the same as they did in Serbia against Napoli and PSG, the scoreline will be a lot worse.
All across the pitch, Liverpool players turned in dreadful performances, with Trent Alexander-Arnold and Daniel Sturridge both substituted at half-time.
In midfield, the Reds were worryingly poor, with Adam Lallana doing himself no favours on his return to the side.
James Milner and Gini Wijnaldum were the two stationed next to the former Southampton man and the trio recorded a worrying statistic against Red Star.
According to UEFA's official website and WhoScored, all three failed to record a single tackle throughout their time on the pitch.
Both Milner and Wijnaldum played the full 90 minutes, while Lallana was substituted in the 79th-minute for Divock Origi.
Liverpool may have dominated much of the game - recording 63% of the possession - but that statistic will still really worry Klopp.
The boss was clearly angry in his post-match interview with the team's performance.
When asked to put the finger on what went wrong, Klopp said: "I only have 10 fingers.
"We had the first big chance with Daniel (Sturridge), a very big one. Each goal in a game like this leads the game in a specific direction.
"The atmosphere noise wise was not a problem for us. But after the second goal they could smell it."
After that display, Klopp will need a response against Fulham on Sunday.
Fabinho, Naby Keita and Xherdan Shaqiri will all be in with a shot of making the starting XI after the Red Star performance.
