There goes the final whistle on a goalless draw at St Mary's, where Jussi Jaaskelainen scoops the man-of-the-match award after pulling off three fine saves to deny Osvaldo, Schneiderlin and Lambert. James Collins wasted the best chance for the visitors, scooping a shot high over the bar from inside the box.
Saints fans appeal after Rat holds on to Ward-Prowse, then Wanyama fires a shot well wide of the target
Late corner for West Ham, Vaz Te puts pressure on and wins another - but Saints are holding firm in defence
Reid gets some attention after landing awkwardly. Hobbles off the pitch and West Ham have used all three subs
West Ham spurn their best chance of the match as Noble pulls the back for James Collins, who leans back and scoops a right-footed shot high over the crossbar from 12 yards out. Shocking miss
Wanyama clears a Jarvis cross and Diame wins a corner for the Hammers, whose fans call for a final effort
Ward-Prowse delivers another free-kick into the box but it skids off the turf for a goal kick. This has 0-0 draw written all over it
Taylor is penalised for handball when it appeared to hit his chest. Ward-Prowse delivers a great free-kick but it just evades Fonte at the far post
It's that man Jaaskelainen again, this time keeping Saints at bay after palming away a right-footed strike from Lambert, who was set up nicely by Rodriguez
Jaaskelainen pulls off another wonderful save, diving to his left to deny Schneiderlin's volley, pushing it wide with a one-handed stop
Lambert drops deep and sprays a long pass which leads to a chance which is blocked by Collins, then another shot is blocked by Reid
West Ham are really missing the combined threat of injured duo Andy Carroll and Stewart Downing - not much cutting edge in the attacking third today
Who can break the deadlock? Rickie Lambert is Sky Bet's 6/1 favourite to do so followed by Jay Rodriguez (8/1) and Pablo Ozvaldo (10/1) while Modibo Maiga and Kevin Nolan are considered the visitors' main threats at 16/1 apiece.
Nolan is flagged offside to spare his embarrassment for making a right mess of a right-footed shot on the edge of the 18-yard box
Osvaldo turns Collins inside out then feeds Lallana, whose first touch is too heavy and allows Jaaskelainen to clear the danger
Saints are building up a head of steam but need to make it count. Osvaldo tries to find Lambert in the box but the ball skids off the wet surface for a goal kick
Rickie Lambert's header from the corner thumps the upright, then Wanyama's follow-up shot bounces off Collins and onto his arm - no penalty though
Wanyama chest controls then volleys from 25 yards out, with Jaaskelainen tipping the ball over for a corner
West Ham win a free-kick, which Noble delivers into the box, only for Saints to clear in scrappy fashion
Gary Neville says Vaz Te was doing a good warm-up at half-time, so could be an option to replace Diame in a short while
Chris Green is back on: This match has been very tight so far - Southampton have been the better team, but I think West Ham will have the last laugh if the likes of Diame and Maiga start being consistent in front of goal.
He's 24, a Croatia international, signed from Lyon in the summer for a reported £8.5m...looks worth every penny
Matt Le Tissier says Schneiderlin's tackle on Diame was a 'dangerous' one and he was lucky not to see a card. The good news is Diame is OK and is playing on
Nick Cary says: This game is close and I can see one goal deciding it. Southampton look the liveliest, maybe Lambert to get the winner.
And there goes the half-time whistle. Diame and Osvaldo had the best chances of the first half, but were both denied by superb saves from Boruc and Jaaskelainen respectively.
The ball breaks to Maiga in the box but he can't get his left-footed shot on target and steers it wide of the upright
Collins loses possession in a dangerous area but Rodriguez's first touch is poor and the chance is gone
Rodriguez breaks down the left and eventually feeds Shaw, who slices his left-footed cross out for a goal kick
Wanyama's break from midfield forces a corner but Collins wins the aerial contest and West Ham clear their lines
Saints clear a cross from Diame and a shot from Noble, then Morrison curls a 25-yard shot just over the crossbar
Noble floats a free-kick into the Southampton box but it poses little threat and is pumped clear with ease
Having seen the replay of the tackle it appears Schneiderlin is lucky not to have seen yellow...he got the ball but got a fair chunk of Diame in the process
Diame goes down under a hefty challenge from Schneiderlin but the referee plays on - much to the anger of West Ham's players
Osvaldo tries a cheeky back-heeled throughball which nearly comes off but runs through to Jaaskelainen as no one read it
Lallana whips in a corner - both teams have now had two each - but Lambert is penalised for climbing
Lambert pounces on a slip by Collins, feeds Osvaldo then gets a lucky ricochet back into his path. His right-footed volley is well saved low down by Jaaskelainen, though
Shaw floats a decent cross into the box but West Ham's defence revel in aerial tests and clear it confidently
Diame lets fly with an ambitious 35-yard drive which whistles inches over the crossbar. Boruc always confident
A decent Hammers move ends with Demel lofting a cross from the right flank over everyone in the box for a throw-in
Noble wins possession to end some fluent Saints passing, although it's in the middle of the pitch so no real threat
Saints are definitely bossing the game now and starting to get their passing game going in slick conditions
That was a great chance for the hosts and it was a superb cross from the left flank by Jay Rodriguez...really should be 1-0
Saints string together a fine passing move which creates a chance for Osvaldo, whose sidefooted shot is brilliantly turned away for a corner by Jaaskelainen
West Ham look hungrier in the early stages and are closing down well. Jarvis breaks down the left but his cross disappoints again and it's easy for Boruc to collect.
Jarvis lets a good attack fizzle out by crossing too deep for a Saints goal kick. Solid start by the Hammers, though
Diame goes on a powerful run into the box and tests Boruc with a close-range shot which is palmed away by the keeper
Boruc gets his first few touches of the ball and uses Wanyama as an option twice rather than pumping it upfield
Collins' free-kick is dealt with brilliantly by Luke Shaw, who will also be looking to shine further up the field today
Billy Mills from Portsmouth says: Can't see anything but a Southampton win today, think West Ham will struggle due to a lack of strikers so am going for 3-1 Souhthampton.
Mark Noble has score three goals in the last three league meetings between West Ham and Southampton; more than any against other league opposition.
