Having lost just three times this season, Liverpool were never going to take their 1-0 defeat to Atletico Madrid well.The only ‘L’s’ Jurgen Klopp’s side have suffered came in the Champions League group stage against Napoli - a group they finished top anyway - and when a youthful side played Aston Villa in the Carabao Cup with the first-team in Qatar for the Club World Cup.Two losses that ultimately didn’t matter all that much.But their 1-0 defeat to Atleti in the first-leg of their last-16 leaves their Champions League future hanging by a thread.It was a frustrating night for the Reds, who dominated possession but couldn’t recover from Saul Niguez’s fourth-minute goal.

They probably should have known what to expect from Diego Simeone’s side but Andy Robertson was clearly annoyed in his post-match interview.

The Scottish left-back criticised them of continuously "falling over" and pointed out they scored from a throw-in that should have been awarded to Liverpool.

That brings us onto referee Szymon Marciniak.

It’s fair to say the officiating from the Pole angered Liverpool players, Klopp and the fans.

So much so that one fan has created a ‘disasterclass thread’ showing six shocking refereeing decisions Marciniak made last night.

They are:

- Awarding a throw-in to Atletico (in which they ultimately scored from)

- Giving a foul for Fabinho’s perfect tackle

- Giving a foul for James Milner’s perfect tackle

- Giving a yellow card for Joe Gomez’s innocuous tackle

- Giving a foul for Mohamed Salah winning the ball in a dangerous position

- Not giving a foul on Alex Oxlade-Chamberlain just out the box

There were no doubt plenty of others - like the blatant handball that he failed to give Liverpool a free-kick for in an attacking position. That one earned Klopp a yellow card for his protests.

Liverpool will now need another famous European performance at Anfield if they want to progress to the quarter-finals.

They’re also going to need a strong referee that will see through Atleti’s playacting and time-wasting.
