Goal: Southampton 1-4 Liverpool (Divock Origi)
If there is any doubt over Origi's first, then there is little about the second. Jordon Ibe drifts inside, slips a ball through to Origi to latches onto it and lashes the ball past Stekelenburg. bar a stunning late comeback, Liverpool are going into the last four.
Van Dijk's effort hits the wall. Liverpool have negotiated the first quarter of the second half. Southampton need some inspiration quickly.
Emre Can booked for a foul on Mane and he will miss the game at Newcastle United on Sunday. Meanwhile, free-kick for Southampton...
Double change for Southampton as James Ward-Prowse and Shane Long replace Cedric and Jordy Classy. Long is straight into the action but only heads wide from a cross from the left.
Daniel Sturridge last 59 minutes before making way for Jordon Ibe. Liverpool look comfortable it must be said despite playing second fiddle in this second half.
Half chance for Mane, who goes through but sees Randall block his right-footed effort. Improved from Southampton in the second half but they are not scything through Liverpool like they did in the first 45 minutes.
Liverpool's third goal is now being given to Divock Origi after replays show he did get a feather on that Alberto Moreno goalbound drive. For what it is worth, don't think it effected Martin Skelenburg's view of the effort as the ball went under him. No offside either.
Southampton need a quick reply here to stand any chance and they test Adam Bogdan for the first time since the early moments of the first half. Graziano Pelle latches onto a through ball but Bogdan gathers at the near post.
Teams back out for the second half at St Mary's and the game is back under way.

Goal: Southampton 1-3 Liverpool (Alberto Moreno)
Into stoppage time in the first half but Liverpool have now put daylight between themselves and Southampton. A corner is only cleared as far as Moreno who drills goalwards and though Divock Origi flirts with the idea of touching it on, the Spaniard's effort flies beyond Stekelenburg - who wants offside. Fantastic turnaround.
Hard not to wax lyrical over not only the two goals in as many minutes from Daniel Sturridge, but the pass for the second goal from Emre Can. The German cuts inside onto his right foot and produces a gorgeous pass with the outside of the boot with finds Sturridge in behind. It has been a stunning start from Liverpool and their decent away form continues.

Take a bow Daniel Sturridge. Joe Allen lofts a ball through to the England forward who initially miss controls it but as the Southampton defence backs off he shifts the ball onto his left foot and fires unerringly into the corner beyond Stekelenberg.
It is all Southampton in the opening quarter of an hour at St Mary's, with little to get excited about if you are a Liverpool fan. Mane and Tadic in particular are causing all sorts of problems for the visitors, who have not been able to get the returning Daniel Sturridge into the game as yet.
