On Tuesday night, Liverpool succumbed to another defeat on the road in the Champions League.
Red Star Belgrade recorded a shock 2-0 victory over Jurgen Klopp's side to blow Group C wide open.
Forward Pavkov scored a first-half brace and Liverpool's star-studded team struggled to break down a resolute Red Star defence.
"I saw a few games like this already and it is really difficult to find your mojo," Klopp said.
"We made life a bit too easy. I don't say it is already serious if you lose twice but we have to make sure it will not not happen again.
"We had a lot of moments when we could get in control of the game and we didn't do it, we just made the wrong decision."
Liverpool have managed to win just three of their last nine matches in all competitions.
Ferdinand posts about Klopp
Manchester United legend Rio Ferdinand shared an image regarding Klopp's record on his Instagram story.
Evidently, the BT Sport pundit was surprised to see Klopp's win percentage lower than the likes of Arsene Wenger, Jose Mourinho and Mauricio Pochettino.
Sir Alex Ferguson spent 21 years in charge of rivals Man United and retired with a 65% Premier League win percentage.
Ferdinand went viral this weekend after a Liverpool fan asked him to take a photograph.
Klopp has been lauded by the English media but the German coach is yet to win a trophy since arriving at Anfield in 2015.
Man City, Man United, Arsenal and Chelsea have all won silverware since Klopp took charge.
The 51-year-old former Borussia Dortmund boss won two Bundesliga titles during his time in Germany but is yet to finisher higher than fourth in the English top division.
Liverpool do remain unbeaten in the Premier League this season and host struggling Fulham on Sunday lunchtime.
