Liverpool beat Chelsea 2-1 in a Friday night trip to Stamford Bridge - handing the new Chelsea boss his first defeat and moving firmly into the top four.
The pre-match team news was that Firmino was ruled out through a groin injury. A big blow for the reds but Coutinho was the man who could come in to replace him.
For Chelsea they welcomed back David Luiz for his second 'debut' for the club. He signed at the end of the transfer window and was in to replace John Terry.
It was Liverpool's little Brazilian, playing his 150th game for Liverpool, who was involved in the first goal. Just after the quarter hour his cross from the left wing was beautifully weighted and found the unlikely figure of Dejan Lovren at the back post to poke the ball home.
More than deserved for the reds.
15 minutes later another unlikely scorer. In his 20th game since his last Liverpool goal - the captain collected a ball from out wide and unleashed a wonderful 30 yard shot that dipped over Courtouis to double Liverpool's lead. Jordan Henderson ran away in delight to celebrate.
There were some boos from the Chelsea fans at half time highlighting the reds impressive performance.
No substitutes at half time but Chelsea gradually improved in the second half as the reds ceded some possession. 10 minutes in and Daniel Sturridge went off - fears of an injury as he went down the tunnel for treatment. Divock Origi chosen to come on.
The change didn't help Liverpool who lost their way for a period and it was Diego Costa who pounced inside the area to grab a goal back. His 5th goal in the 5 games this season.
After a few more difficult minutes - the reds fought their way back into the game and Divock Origi probably should have made it 3 when he headed down low at the Chelsea keeper from 6 yards.
The game ended in frenetic fashion - Antonio Conte making a triple substitution with 8 minutes remaining but the sight of former LFC loanee Victor Moses wasn't one to trouble the visiting Liverpudlians.
The reds went on to land another very important win in what has now been a solid start to the Premier League season.
League Cup action next as the reds travel to Derby in midweek.
