Jurgen Klopp's Liverpool have overran a miserable Southampton side earlier this morning, hitting six past Maarten Stekelenburg to seal a League Cup semi-final.

Making six changes to the side that defeated Swansea last Sunday 1-0, Klopp took a youthful team to the South Coast to take on Southampton who fieled quite a strong side.

Klopp saw his bold approach rewarded with a 6-1 win at St. Mary's against a Saints side missing their captain Jose Fonte who was replaced by Steven Caulker who had a torrid evening at the back.

It took Southampton just 42 seconds to go 1-0 up, with Saido Mane heading home from Ryan Bertrand's cross, giving Bodgan no chance from point-blank range. Mane's goal was the fastest ever scored in League Cup history.

The early goal set up a tense contest with some high temp, end-to-end football enthralling St. Mary's. As the intensity heightened and the pace increased, Sturridge came to the fore, latching on to Allen's well weighted throughball.

Sturridge was able to fool Caulker into showing his right side, enabling Sturridge to smash it home on his favoured left foot. Moments later, Can produced a perfect finessed pass to Sturridge who then finished it first time to put the Reds ahead.

Just before half-time it got worst for the Saints as Moreno drilled in a powerful strike following Virgil van Dijk's attempted clearance from a corner. Replays show it was turned in by Divock Origi who was onside, giving the youngster his first Liverpool goal.

Origi made it 4-1 after half-time with a brilliant 'sergio aguero' like finish, punishing a sluggish Southampton attack.

Jordan Ibe, privider for Origi's second, added Liverpool's fifth just minutes later, chesting the ball down from Moreno's cross to drill it in to the bottom corner.

Origi sealed his hat-trick thanks to Australian subsitute Brad Smith who delivered a stunning cross to gift the striker with his second career hat-trick.

The win sets up a two-legged semi-final tie with Stoke City to be played on January 6 with the first leg taking place at the Britannia.

The other tie will see Everton take on the holders Manchester City. The feel good factor is back at Liverpool who are now looking to claim their ninth English League Cup.
