A first-half brace from Virgil van Dijk lifted Liverpool 11 points clear at the top of the Premier League in a 2-1 win over Brighton that was filled with drama after the sending off of home goalkeeper Alisson.
The Brazilian was dismissed on 76 minutes as he raced out of his area to handle an attempted chip by Brighton substitute Leandro Trossard.
Spanish replacement Adrian came on but his first act was to pick the ball out of the net as Lewis Dunk rolled the free-kick past the Liverpool wall and an unprepared goalkeeper.
The loss in midweek of influential midfielder Fabinho had taken the gloss off a successful period for Jurgen Klopp's side, with an ankle injury ruling the Brazilian out for six weeks.
But the mood around Anfield before kick-off was certainly lifted when news came through from the north-east that their rivals Manchester City had unexpectedly dropped two points at Newcastle.
It did not take long for that mood to improve still further as Liverpool set about their task of attempting to move 11 points clear of Pep Guardiola's side, the defending champions and the team still seen as their greatest challengers.
It took 18 minutes for Klopp's men to take a deserved lead after Pascal Gross fouled Alex Oxlade-Chamberlain outside the Brighton area.
Trent Alexander-Arnold floated in the perfect free-kick and van Dijk rose powerfully above Adam Webster to head in his second goal of the season and first since the opening day of the season.
