Liverpool showed a ruthless streak to come from behind to beat Arsenal at the Emirates. In the first-half they played the part of spectators, but in the second it was almost as if a different team had come out.
Liverpool's Philippe Coutinho celebrates scoring their third goal with Nathaniel Clyne
Simon Mignolet 7/10 - Despite conceding three, the Belgian 'keeper performed relatively well. He had lost the spot of number one during the summer when Klopp signed German Lorus Karius from Mainz. However, the penalty save will have done his chances of retaining that jersey no harm at all.
Nathaniel Clyne 7/10 - Performed well on the right side of the back four and was relatively untroubled by Alex Iwobi. Set up Coutinho for his second, and Liverpool's third, when crossing from the right flank after a long run. Still, he looks better in the opposition half than he does in his own.
Dejan Lovren 5/10 - With no Olivier Giroud in the team, Lovren should have been at ease is the commanding presence in the Liverpool defence. Alexis Sanchez hardly ran his ragged but he turned his back when Oxlade-Chamberlain shot for Arsenal's second, perhaps reminding us of his weaknesses.
Ragnar Klavan 6/10 - Making his debut for Liverpool, the Estonian who is capped 113 times, performed relatively well. He looked strong in the air and made several clearances from set pieces. One blemish on the performance would have been Arsenal's third goal however, as he was out jumped by Callum Chambers.
Alberto Moreno 4/10 - By far the worst player on the bench. Defensively incompetent for the entire match giving away the penalty before allowing Theo Walcott to redeem himself 68 seconds later. With James Milner on the verge of a return, this could well be the Spaniard's last appearance under Klopp for a while.
Jordan Henderson 6/10 - The Liverpool captain played in the holding role again. In the first-half his side looked short in the middle go the park, as Arsenal's midfield overran them, but controlled it better in the second. Was neither dire or outstanding.
Adam Lallana 7/10 - Like Henderson, went missing in the first period but took his goal early in the second half extremely well. At the Euros it was his finishing that let him down, but after controlling the ball on his chest, he struck it past Petr Cech with his weaker right foot. Industrious as ever, also.
Georginio Wijnadum 6/10 - Again, was missing for the first-half. However, he showed his quality in the second half with an exquisite assist for Lallana. He works ruthlessly hard for his team and will only get better as he becomes more familiar with his new teammates.
Sadio Mane 8/10 - Another debutant, £34 million man Mane will remember this one for some time. His strength, power and skill were too much for Nacho Monreal and his goal was breathtaking. Collecting the ball on the byline, he cut past Monreal before dribbling into the box and smashing into Cech's top corner.
Coutinho 9/10 - Sky Sports awarded him the man of the match award, and it wouldn't have taken a rocket scientist to work that one out. Scored with a free-kick that Cech wouldn't have saved even if he was on a step ladder. Started the move that led to Lallana's goal and played the final pass to Mane for his strike. Came off as an injury precaution in the dying embers of the match, immediately making Liverpool look weaker.
Roberto Firmino 6/10 - Run of the mill performance for the Brazilian as he had to settle for being in his compatriot's shadow. Was ineffectual but did everything required of him from Klopp, chasing every ball. Will have worse games, will have better.
