Liverpool came from a two-goal deficit but then suffered a setback from Leandro Trossard's third goal, giving Brighton a point in Saturday's 3-3 draw at Anfield.
A quick double strike from Trossard gave Brighton an early and deserved lead. But Liverpool struck back, Roberto Firmino scoring twice just before half-time before Adam Webster's own goal put the hosts ahead. But Trossard equalized with seven minutes remaining.
Roberto De Zerbi's tenure as Brighton manager got off to a perfect start as the visitors took the lead after just three minutes and 48 seconds.
Moises Caicedo pressed Jordan Henderson on the edge of the Liverpool box and passed the ball to Danny Welbeck. The Brighton striker passed the ball to Trossard, who fired the opening goal into the bottom corner.
The hosts, who had made their worst Premier League start in seven years, were overwhelmed by the visitors while Alisson made a plethora of saves.
The Brazilian made a save against Trossard before Brighton's star completed a brutally quick counterattack with an almost identical finish to his opening goal.
Liverpool fought back into the game with sheer willpower. The Reds brought the ball to Mohamed Salah in the penalty area twice in quick succession. The Egyptian was initially denied by Robert Sanchez but was soon dropped to Roberto Firmino, who halved Brighton's lead at half-time.
Jürgen Klopp came on for Luis Diaz at the break and it took the Colombian less than ten minutes to make the desired impact. Diaz led a Liverpool attack down the left flank and played the ball to Firmino in the box before equalizing for Liverpool.
The lively substitute was also involved in Liverpool's third goal: he won a corner kick that Trent Alexander-Arnold executed with great vigour. Sanchez deflected the ball towards his team-mate Adam Webster and from there into the Brighton net.
But the guests were undeterred. Kaoru Mitoma came off the bench for Brighton before De Zerbi changed his line-up and Trossard moved to the right flank. That combination led to Brighton's third as Mitoma's cross clipped through Virgil van Dijk's holographic intercept and pocketed Trossard for the famous third.
