That was immensely enjoyable. From a personal preference I was quite happy to see a game in which pointless possession and passing around in defence was seen as the route to victory; we had less possession and made far fewer passes than the corresponding fixture last season - which we lost 3-1 - but we totally dominated City, working feverishly hard to ensure City had no time to dwell on the ball, forcing them to cough up possession time and again. Klopp's style of football and management, indeed his whole personality, is a much better fit than Rodgers.
It was also achieved with our two best strikers still not ready to start, so Klopp employed a rather interesting 4-6-0 formation, with Firmino, Coutinho and Lallana dancing in and out of a befuddled City defence and midfield. Firmino was probably the closest we had to a striker in terms of formation, and he rewarded Klopp with his best performance as a Liverpool player. Pellegrino proved again that he is not a top quality manager, and his decision to play Toure and Fernando as a midfield two lost them the game in the first 45 minutes, as they were at times facing 5 Liverpool players in the midfield. This makes the home Palace defeat against the execrable Pardew even more galling, but if we can start playing like this at Anfield, we'll all be happy.
De Bruyne, Hart and Aguero were excellent, but they were the only players who looked the part of Champions; the rest were dreadful.
Ratings below
Mignolet (7) Much better than his poor display against Palace. Some smart saves and booming kicks were very welcome indeed. Had no chance with the fabulous Aguero goal. His distribution is still too slow and erratic, but a late charge out of is area showed good reading of the danger.
Skrtel (8) Very good indeed. Always in the right place, made several great headed clearances and scored a great goal with a shot so hard and fast Hart only started to move after it had gone past him. Extra point for that.
Lovren (7) Will have had most Liverpool fans nervous at the start, but performed well, throwing himself into challenges and clearances
Clyne (7) City always seem to play more intricate and dangerous football on the left, which kept Clyne busy, but he is a very good player and coped well.
Moreno (7) He's much better when he has to simply compete physically, with pace or power, and he had his ideal adversary in the pacy and one-dimensional Navas. far less happy when the superlative De Bruyne came near, but his attacking prowess was great to watch
Lucas (6) Had little to do, as City's midfield were pinned so far back ether was acres of space for Lucas to move into. Caught out by the pace and movement of Aguero who skinned him on the way to scoring, but he wasn't the only one. Booked, so will serve a suspension.
Can (8) What a massive improvement. A game in which his undoubted powerful presence was actually aligned to an end product. Blew City away with some wrecking ball play, and then conjures up a beautiful back heel to set up another goal.
Milner (8) A blur of industry and effort, he was a building block for the total midfield control we enjoyed and used the ball well. Captain's display, great to have him back in the side and playing like this, after a few weeks of toil and mediocrity.
Lallana (8) Another who helped orchestrate this one-sided display. Finally showed some end product and genuine quality, as opposed to slow-motion Cruyff turns and harmless tricks and flicks - here he was causing damage all over the pitch, and one dummy that wrong-footed an admittedly almost entirely hapless defence, was simply glorious. This is what we expect from Liverpool players.
Firmino (9) He is unfortunate that his price-tag and reputation perhaps had some fans expecting Suarez-type quality. I was one of many left utterly underwhelmed, but this was more like it. He doesn't have much genuine pace, and isn't exactly a deadly finisher - as evidenced by the plethora of chances he wasted - but he always wants the ball, and when he has the freedom to move around the pitch, he can do real damage with it. Caused utter mayhem and left City dazed with his movement and passing. Should have scored three.
Coutinho (9) One of those games in which his willow-the-wisp playing style is allied with the aggression and venom of a black mamba. He was unplayable at times, darting head up into City's final third time and again, City's players trying to tackle smoke. Wow.
