Jurgen Klopp faced the biggest test of his brief Liverpool career when his team took on an under-pressure Jose Mourinho and Chelsea.
The defending champions have yet to get their season started, and after today's 3-1 loss their title challenge is all but done before after picking up just 11 points from 11 games.
The day started out so well for Mourinho, as Ramires out his team in front in the opening minutes of the game.

But still the champions never felt in control, and this was typified by Diego Costa. The striker was up to his old tricks by lashing out against Martin Skrtel.

Then Phillippe Coutinho levelled the scores
with a controversial goal deep into injury time.

But the Brazilian playmaker wasn't done, scoring again in the 74th minute to give Liverpool the lead before Christian Benteke added a third to hand Chelsea their sixth league defeat of the season - an all-time high for a Jose Mourinho team.

And opposing fans were quick to rub salt into the wounds.
