Southampton 3-2 West Ham
What a match! Southampton come away with the win against 10-man West Ham.
Charlie Austin
A cool finish under huge pressue from Charlie Austin.
This has been a thriller!
Southampton 2-2 West Ham
DRAMA! Maya Yoshida is bundled down by Pablo Zabaleta.
Southampton have their second penalty of the match. In the 90th minute!
Southampton 2-2 West Ham
Woah that was close! Nathan Redmond's strike is deflected on to the bar and out for a corner.
I think Joe Hart got a slight finger to it, and it may have taken a deflection off Jose Fonte, too.
Southampton 2-2 West Ham
Southampton break! Maya Yoshida pumps the ball down field and Shane Long is trying to do something with it.
But the Saints sub is wrestled off the ball.
The hosts build up again and Cedric Soares' ball is headed home by Long...but the whistle has already gone for a foul on Joe Hart.
Southampton 2-2 West Ham
Pedro Obiang rescues West Ham as Cedric Soares charges up the right.
Southampton's resulting corner comes in from James Ward Prowse and Shane Long, who's just come on as a sub, can't quite get on the end of it.
Southampton 2-2 West Ham
Charlie Austin is on for Manolo Gabbiadini.
Southampton 2-2 West Ham
Not bad from Nathan Redmond. Not bad at all.
The Saints man strikes from distance but his effort goes just wide of the post.
Southampton 2-2 West Ham
Southampton try and push forward to find a winner but play is halted when Maya Yoshida clatters Diafra Sakho.
It looks like Saints are going to make their final changes, with Charlie Austin ready and waiting on the sidelines.
Southampton 2-2 West Ham
Pedro Obiang comes on in place of Declan Rice and the referee feels the need to have a chat to Slaven Bilic, who is very animated on the side line.
Javier Hernandez
My word! What a comeback!
Javier Hernandez brings West Ham level by doing what he does best - poaching.
The former Manchester United forward pokes home after Diafra Sakho's header came off the woodwork.
Southampton 2-1 West Ham
James Ward-Prowse bangs a powerful cross into the box and it's headed away with Jose Fonte.
Ten-man West Ham survive another spell of pressure.
Southampton 2-1 West Ham
It's gone a bit quiet in the last few minutes.
Maya Yoshida punts a looping ball over the top but Nathan Redmond can't latch on to it.
Jack Stephens, having survived being almost decapitated by Marko Arnautovic's elbow earlier on, makes a rare dart forward.
Saints are rewarded with a corner.
Southampton 2-1 West Ham
A double sub by West Ham.
Diafra Sakho and Edimilson Fernandes come on for Antonio and Ayew.
This was Antonio's first match after four months out injured.
Southampton 2-1 West Ham
Mario Lemina, who was involved in quite a few battles out there today on his debut, is replaced by James Ward-Prowse for Southampton.
Slaven Bilic is getting Diafra Sakho ready to come on for the Hammers.
Southampton 2-1 West Ham
Joe Hart with a double punch to deny Southampton.
First of all he gets his hands on to an in-swinging cross and then a shot from distance from Dusan Tadic.
The England stopper did well on both occasions.
Southampton 2-1 West Ham
At the other end, Hernandez has another go at testing Fraser Forster.
At times, West Ham don't look like they're a man down.
Southampton 2-1 West Ham
A sweet, sweet strike from Manolo Gabbidani goes just off the cross bar.
He took his time to take his shot and it was so close to squeezing into Joe Hart's net.
Southampton 2-1 West Ham
West Ham go nuts. They reckon Jack Stephens has handled the ball in the box as he's tried to clear from a Hammers throw-in.
It looks like the Saints defender kept his arms by his side and it's come off the lower bit of his shoulder.
A difficult one to call, that.
