On a cloudy evening in west london , the blues hosted Liverpool looking to win just the second time in their last 10 games against the reds.
It was the reds who started brightly in the opening five minutes but a miserable first half started when Christensen gave a freekick away on the edge of the box before Alexander-Arnold hit a thunderbolt into the top right corner.
The evening went from bad to worse when Emerson limped off with a muscle injury in the 16th minute. A reoccurrence of the injury he suffered in the last international break. The Italian was struggling and Frank Lampard's defensive headaches intensified.
Chelsea thought they were level in the 28th minute when Azpilicueta pounced on a loose ball before hitting a shot under Adrian and into the back of the net but it was cruelly and correctly disallowed much to the dismay of the Chelsea Captain and the cheers from the reds fans.
Much more sorrow was on the way for the blues as Alonso failed to handle firmino in the box who rises high to head in Liverpool's second goal of the game.
Such were the misery the blues were facing in the first half; they gave away two game-deciding penalties, couldn't defend them properly and they were licking their wounds as another defender in form of Christensen was caught on the knee and he joined Emerson in the treatment room.
Kepa Arrizabalaga made two crucial saves at the beginning of the second half to keep the blues in the game but kante who made three tackles in the game and 11 recoveries in the game brought the blues back in it with a deft finish into the top corner.
From that moment, the blues hassled and pressed forward with renewed confidence and belief, they took control of the game and went in search of an equalizer and it was only a Michy Batshuayi header which went wide of the post and a Mason Mount volley which sailed high over the crossbar that prevented Chelsea from picking up at least a point against a Liverpool side who simply committed bodies backwards during a period of relentless Chelsea pressure.
It was not a top performance from Klopp's men. It was just about being clinical because Chelsea certainly had their moments in the first half and dominated proceedings in the second. The reds didn't create an awful lot of chances and likes of Mane and Salah were largely ineffective.
A loss to Liverpool was certainly not surprising due to the golf in class between the two teams.
Although, The sight of Christensen coming off with a knee problem will leave Lampard with a lot to ponder on.
