Southampton are having to push forward looking for an equaliser, and that's giving West Ham loads of space to exploit on the break.

The hosts regroup this time, but it's only a moment's rest as the Hammers pour forward again through Michail Antonio and Andy Carroll.

Felipe Anderson is causing havoc right now.

He drops a shoulder and sets off down the line before pulling the ball back into the path of Lucas Perez, but a last-ditch lunge from Jannik Vestergaard blocks the former Arsenal man's strike from inside the box.

Stat of the night. Possibly the week. Maybe the season.

Felipe Anderson is a man in form - after just one goal in his opening 10 Premier League appearances, he has scored seven goals in his last nine.

Neil Kennedy: Go one down after 50 minutes. 8 minutes later and it's 2-1 up thanks to 2 magnificent goals from Felipe Anderson. That's what you pay £45million for - COYI!!!

Alex Haworth: Putting Felipe Anderson in my fantasy football team might be the best decision I've made this year.

Sean Turner: You couldn't ask Santa if he does lottery numbers as well, could you?

Santa definitely delivered on my request at the start of the second half, didn't he? Thanks, Santa!

This has turned into some game.

Southampton whip it wide to Matt Targett, who curls in a low ball across the area and it's scrambled clear by the visitors.

Corner.

West Ham want a penalty as Robert Snodgrass goes down in the box under pressure from Jannik Vestergaard, Craig Pawson waves the appeals away...

Josh Trott: Please stop posting things my brother tweets to your feed (see 20:37) - he's now doing a Danny Ings and won't shut up about it.

Sorry, Josh. If it helps, Ralph Hasenhuttl has now taken Danny Ings off as well...

Might be 30 years old, but my belief in Santa Claus never waivered... half-time Christmas goals wish well and truly answered.

Can you believe the organisation from Southampton to leave themselves that open from that situation? Stuart Armstrong had a shot blocked on the edge of the box, and from there, West Ham had three or four men over on the break. To be fair, West Ham worked that brilliantly.

Great strike from Stuart Armstrong, superb save from Lukasz Fabianski to push the Southampton midfielder's curling long-range effort wide of the post.

There were just 168 seconds between Nathan Redmond and Felipe Anderson's goals.

Christopher Davison: Twice in a year a player has punched the ball in against West Ham and the refs have allowed it

Here comes the Carroll(ry)... the Hammers bring their giant front-man off the bench and he's immediately in the thick of it with a wild tackle that somehow doesn't warrant a caution.

So that Southampton opener has actually gone down as an Angelo Ogbonna own goal...

London buses, isn't it? We've barely had a strike on target, and then we get two goals in no time. Anderson has looked like the one who can open the door. Fantastic strike. The goalkeeper barely gets down to it before it's past him.

Lukasz Fabianski's gone over the linesman to say: "How is that not offside?" Matt Targett was on the ground in an offside position, but he obviously wasn't interfering with play. Nathan Redmond certainly wasn't offside. I think it was Michail Antonio who was playing him on. As much as Antonio is fantastic going forward, he's probably three or four yards further back than he should be. When you play someone out of position, and you ask them to work as part of a unit, it doesn't always function. They've been caught out there, West Ham.
