The Brazilian duo, ably assisted by Mohamed Salah, tore the Seagulls to shreds in a thumping 5-1 victory.
Emre Can opened the scoring before Firmino added a quickfire second and then doubled his tally in the second half.
Glenn Murray pulled one back from the penalty spot but Coutinho hit the fourth and then forced an own-goal from Lewis Dunk to complete the rout.
Here is how we rated the Reds
LIVERPOOL
Mignolet 7 – Was crucified for costly errors last month but his incredible reflex-save from Murray’s close-range strike was effectively an assist as Liverpool countered with breathtaking speed for their third on the back of his stunning stop.
Alexander-Arnold 6 – A goal-saving challenge from Izquierdo was crucial as it would have allowed Brighton an avenue back into the game with the score at 3-1. Composed and mature from a defensive perspective and tried to bomb forward when the opportunity arose.
Lovren 7 – An improved performance on recent weeks for the Croatian who stepped up to the responsibility of having two out-of-position defenders either side of him. Swept up on the deck and commanded in the air, the Reds will hope he can display this level of confidence on a consistent basis.
Can 7 – The German was used as a full-back at times last season and struggled there but moving inside to centre-back was a much smoother transition. A centre-half’s header for the opener – his first Premier League goal of the campaign – and Klopp’s decision to use Can as the man to bring the ball out the back worked a treat.
Robertson 6 – Finally back in the first-team fold, Robertson was in a surprising left-wing back role but when it comes to dribbling and pace, Alberto Moreno is the better man for the position. However, he offered plenty of quality with crosses into the box and his defensive shape is miles better than the Spaniard.
Henderson 6 – Momentum really seems to slow down when Henderson gets on the ball and his first-time dinks over the top are always horribly off target. From the defensive side, was much more solid than in recent weeks as he and Milner operated in a two-man pivot which never really looked troubled.
Wijnaldum 5 – Predictably, was really uncomfortable on the left side of Liverpool’s back three. Awkwardly kept cutting onto his right foot to make less than convincing passes back to Mignolet but closing in on 100 career goals, you can bet he’s seldom been deployed as a defender.
Milner 7 – Diving in full blooded to make a tackle on the halfway line at 5-1 up encapsulated what Milner gave Liverpool – leadership. Didn’t stop running and was a real rock in the middle to allow the freedom of movement for flair players like Coutinho.
Salah 7 – Failed to make it five consecutive games with a goal but he was electric all the same. Superb assist for Firmino’s second as he slalomed past Brighton defenders on the edge of the box before laying it off for the Brazilian to finish.
Coutinho 9 – Liverpool fans must savour the opportunities to see him play because the magician was magnificent. Twisting, turning, scoring and assisting, the Brazilian was the man of the day. He made three assists, first for Can, then for Firmino before topping off his display with a clever free-kick before seeing a shot diverted into his own net by Dunk.
Firmino 8 – Easy to see why the Brazilian is one of Klopp’s favourites. Dribbling, passing, interceptions, work rate, movement and against Brighton – goals. A quality performance from Firmino and only Coutinho edged him out as the Reds premier player.

SUBS
Oxlade-Chamberlain 6 – Came on for Salah with 10 minutes remaining and was his usual explosive self as he tried to make an imprint on a game which was already won.
