"It is clearly something they work on in training and they are reaping the rewards".
Liverpool jumped a point above United, which hosts Chelsea on Sunday.
Liverpool are the division's form team with an unrivalled 19 points over the past eight games.
Tammy Abraham got one back with a deflected shot, but Brighton made it four when Jurgen Locadia converted a low cross in the 90th minute. This result and moreso, the nature of the game itself, therefore sends out a clear signal of intent from the Merseysiders.
It is Liverpool's best attack since 2013-14's near-title winning campaign, when Brendan Rodgers' side put up 110 in all competitions. Salah netted his 31st goal of the season in a move that was far more about the assist as Oxlade-Chamberlain bullied his way through the West Ham midfield before prodding the ball through to Salah.
Only Nathaniel Clyne is out injured, so team selection will be tricky.
West Ham's most important player was then able to smash an outstanding effort from a 30-yard free-kick which swerved massively. Missed two one-on-ones in the match before finally scoring from a Robertson cross. This can hardly be attributed to their new signing Virgil Van Dijk as each clean sheet has come with a different partnership in central defence. We worked most of the week to try and find a way that we could curtail them the best we could.
The Hammers are unbeaten in their last three visits to this ground, winning once and drawing the last two in a row.
Klopp said he was proud at how forward Roberto Firmino had conducted himself following an allegation of "discriminatory conduct" during last month's Merseyside derby in the FA Cup. "Since I have been at the club he has been huge".
Adrian - 6 - West Ham's No.1 was unable to keep out Can's opening strike in the first half.
What has helped the Hammers climb away from danger has been the increased amount of goals they've been able to score in recent weeks.
Mohamed Salah scored his 18th goal in his last 17 games on Saturday. With Liverpool dominating possession, he didn't have a lot to do in the game.
