London: A clinical Liverpool beat Arsenal 2-0 to cut Manchester City's once double-digit lead at the top of the Premier League table to a single point on Wednesday, leaving the title race wide open. An Arsenal side on a five-game winning run in the league and in fourth place represented a big obstacle to Klopp's title chasers and were the better side in the first half.
But the game tipped decisively early in a frenetic second period as Liverpool extended their own relentless run to nine consecutive league wins.
Their breakthrough came shortly after a misplaced backpass had almost gifted Arsenal a goal, Portuguese Diogo Jota getting ahead of the London side's defence on 54 minutes to beat goalkeeper Aaron Ramsdale at his near post.
Roberto Firmino sewed up a crucial three points eight minutes later, squeezing a shot under the Arsenal goalkeeper again after the hosts had twice failed to clear the ball.
Liverpool's title destiny is now very much in their own hands as they still have to visit City in April.
While the result was a blow to Arsenal they remain fourth in the table, one point above Manchester United having played two games fewer.
Arsenal more than matched Liverpool for long periods but the game ultimately swung shortly after the interval.
A misplaced backpass by Thiago let in Martin Odegaard who looked poised to score but Alisson made a superb save.
Minutes later Jota fired the visitors ahead to knock the stuffing out of the hosts.
Firmino, who came off the bench along with Mohamed Salah who surprisingly did not start, then produced a neat flick to convert Andy Robertson's cross after Arsenal were guilty of not getting the ball clear on several occasions.
Tottenham Hotspur kept themselves in the hunt for a top-four finish in the Premier League with goals by Cristian Romero and Harry Kane bagging a 2-0 win at out-of-form Brighton & Hove Albion.
A dismal first half on a rainy night on the south coast was almost devoid of goalmouth action until central defender Romero deflected in Dejan Kulusevski's shot in the 37th minute to open his account for the club.
Tottenham were far brighter than their hosts in the second half and doubled the lead with a textbook counter-attack rounded off by Kane's unerring finish in the 57th minute.
It was Kane's 95th goal in 139 appearance away from home in the Premier League, taking him past Wayne Rooney with whom he had previously shared the record.
