Another booking. James Tomkins collects one for a handball that stops Dusan Tadic in his tracks. 

We have our first sighting of Andy Carroll in his natural element - tracking on to that hanging high ball lofted in from the flank. 

He connects and directs it downwards but there's not enough power. Easily collected.

Oriol Romeu doesn't look the type to be too abashed at picking up a booking and he's got one here. 

A cynical chop to stop West Ham picking up the loose ball to counter. That's his fifth of the season and he'll miss the next match. 

Bad news for Dusan Tadic - that opening goal's been taken away from him...

Cuco Martina goes into the book - he hauled down Enner Valencia. Bit of a silly challenge that, Valencia wasn't really going anywhere. 

Another little tactical switch to tell you about - Carl Jenkinson is now at right-back, with James Tomkins going to the left. 

Jenkinson is already finding loads of space down the right wing. This switch could be a fruitful one in time. West Ham are certainly looking much improved...

James Collins deserves a goal just for his defensive work in that first half and he nearly has one here - his header cleared off the line!

But oh my, Andy Carroll. He booms one over the bar from the edge of the six-yard box as the ball comes back in. 

Not the return he will have been dreaming about...

Two changes to tell you about. 

Andy Carroll is on, Mauro Zarate the man coming off. 

And Manuel Lanzini also makes his return from injury - he comes on for Alex Song. Two pretty attacking moves from Slaven Bilic. 

Will it pay off?

We are back under way.

What next for Slaven Bilic and company then? 

Striker Andy Carroll is back, on the bench, and warming up as we speak...

I honestly can't remember a decent West Ham chance in this half. There just hasn't been one. 

A very disappointing showing from the home side.

One minute added on. 

But only Southampton look like scoring right now.

Make that three chances as Dusan Tadic fires straight at Adrian when well-placed outside the box. 

Two very good chances for Southampton to double their lead before the break. 

Jose Fonte's header from a corner is clawed away by Adrian, before Sadio Mane can't get a clean shot away when played in behind. 

This is not looking good for the Hammers...

Under five to go before the break.

Southampton have had all the territory...

James Collins is having a brilliant game though. 

He makes another great clearance from a Saints free-kick that threatened to swirl its way towards danger at the back post. Virgil van Dijk was ready to pounce on it.

Poor from Mauro Zarate. He gives the ball away to Steven Davis in midfield before chopping the Southampton man down in frustration. It was a lazy trip.

Slaven Bilic will be wanting much more than this...

Almost!

Steven Davis with a turn and run on goal before firing just wide of the far post. Adrian was gone. Stricken is the word.

A word of sympathy for James Tomkins, who's playing with a military-grade shiner today. 

If I can find any pictures I'll dig them out, but it really is a massively bruised eye.

This first half seems to have flown by. Just 15 minutes left for West Ham to get back into this before half-time. 

Some clever keep-ball from the hosts and signs Southampton are dropping deep, but this move comes to naught as Mauro Zarate's low cross is easily gathered.
