Substitute Sadio Mane scored twice as Southampton recovered from being 2-0 down at half-time to stun Liverpool at St Mary’s.
Graziano Pelle was also on target for Saints with a long-range effort while Mane also saw a penalty well saved by Simon Mignolet in dramatic second 45 minutes.
The stunning turnaround left Liverpool looking shellshocked at the final whistle after Jurgen KloppÂ’s side utterly dominated the first period.
The Merseysiders took the lead when Philippe Coutinho drifted in from the left and fired a low, fizzing drive beyond Fraser Forster from 25 yards.
Liverpool doubled their advantage just three minutes later when Divock Origi fed Daniel Sturridge in the area and the England striker took a touch before firing left-footed past Forster.
The Reds at this stage were rampant and another sweeping counter-attack saw Joe Allen played through but his low shot was superbly blocked by Forster.
Allen had the ball in the back of the net moments later but his celebrations were cut short by a late offside flag against Mamadou Sakho.
Southampton had a great chance to get back into the game early in the second half when Martin Skrtel hauled down Pelle in the penalty area. However, Mane Â– on as a half-time substitute Â– saw his spot-kick well saved by Mignolet.
The Saints did haul themselves back into the match later when Pelle fed Mane who escaped the attentions of Sakho before powering the ball into the corner.
Liverpool brought on Christian Benteke for Sturridge with 20 minutes remaining and the Belgian striker could have sealed the points for Liverpool but he dragged his shot wide from Adam LallanaÂ’s pass.
Benteke was made to pay dearly for that miss when Pelle collected the ball on the edge of the area and curled a wonderful effort into the top corner.
With just four minutes remaining, Mane drilled home a dramatic winner after capitalising on some hesitant defending by Mignolet and Skrtel.
The win moves Southampton above Stoke and back into seventh place with Liverpool three points further back in ninth spot.
