Mohamed Salah and Roberto Firmino set up goals for each other as Liverpool won 2-0 on Virgil van Dijk's return to Southampton
Salah laid on the opener for Firmino inside six minutes and the Brazilian returned the favour with a sublime back-heel as the Egyptian notched his 22nd Premier League goal of the season just before half-time
Southampton had their chances to leave a blemish on the latest chapter of Van Dijk's career, but he tasted victory for in the league for the first time  to leave the Saints in the bottom three after one win in an alarming 14-game run
Liverpool, meanwhile, are looking up rather than down with Jurgen Klopp's 50th win as Reds boss moving them to within two points of second-placed Manchester United following their defeat at Newcastle
Klopp predicted a hostile reception for Van Dijk and that proved correct as the defender's every touch was vehemently booed by the home faithful, including a clearance which led to Liverpool's opener
Centre-back Wesley Hoedt failed to deal with a long ball, allowing Salah to race in behind and square for Firmino to apply the finishing touch to a clinical counter
Liverpool failed to build on their early advantage though, allowing Southampton - who had the lion share of possession in the first half - to steady and create three chances
Pierre-Emile Hojbjerg registered Saints' first attempt on target on 18 minutes but Loris Karius was quick off his line to thwart the midfielder's drive after he got inside Andrew Robertson
A frantic 29th minute saw January signing Guido Carrillo head a James Ward-Prowse cross straight at Karius before Dusan returned the favour for the Saints midfielder, whose header drew a fine fingertip save from the Reds stopper
Liverpool awoke from their slumber and a sensational second came three minutes before the break as Firmino dissected the Saints defence with a sublime back-heel, releasing Salah to stroke the ball beyond Alex McCarthy with a first-time finish
As Van Dijk soaked up Saints' attempt at a second-half fight, Liverpool sat back and utilised their rapid counter attacks, although, with the damage done in the first half, no further goals were needed
 "We are in one situation, but we have to keep going, keep fighting
 I am convinced we have got good pace to try to win the next game
 It will be long until the end, we have to be there, recover our mentality and in football everything can change in two or three weeks
" "It was mature
 We scored two wonderful goals and could have scored more in the second half
 We deserved the three points, got a clean sheet and no injuries - nearly perfect
"There were certainly question marks over Salah's return to the Premier League when Liverpool splashed more than £30m on him in the summer - but as debut seasons go, they don't come much better than the Egyptian's at Anfield
He effortlessly dispatched Firmino's back-heel to take his goals tally for the season 29, 22 of which have come in the league
 With only Harry Kane able to boast a better return, the signing of Salah looks as shrewd as any
The fifth round of the FA Cup takes centre stage next weekend, with Southampton travelling to West Brom, who eliminated Liverpool in the previous round
 Liverpool, meanwhile, travel to Porto on Wednesday in the Champions League
