"London Calling" is blasting out over the PA as we get ready for this clash between two of the teams to come up from the Championship last season.
If you fancy a flutter on today's game, our friends at Sky Bet tell us that it is 5/6 for a West Ham win, 3/1 for Southampton while the draw is 11/4. Head over to www.skybet.com for more offers on the action from Upton Park.
West Ham have scored 88% of their goals in the first half so far this term, so Artur Boruc can expect to be busy on his Saints debut. Saints have leaked 20 goals so far this season, and thrown away 11 potential points from winning positions.
More optimistic prediction here from Adam Rutland on the other side of the world: "The view from Jakarta, Indonesia, is that Saints will nick an end to end, mistake filled, game right at the death. Mayuka will come off the bench and use that pace of his to score a 92nd min winner!"
The last top-flight meeting between these two clubs at the Boleyn Ground was a 1-0 win for the Saints in December 2002. The winning goal came from James Beattie, last seen at Sheffield United last season.
Tom Pointin not feeling optinmistic: "Poor team out today from Adkins, can't stand Guly, should be playing Mayuka instead with some pace and energy in the team. We will miss Ramirez, I think Saints will unfortunately lose 2-1"
Goerge Bennett: "A draw will be a good result for the Saints today, Clyne's return will bring confidence to the defence & a one-one draw seems a realistic result to me."
Darragh O'Connor is Rosscommon, Ireland is feeling confident: "3-1 to the Hammers"
Dave Vasse questions Nigel Adkins' team selection: "Real dismay here at Upton Park. What does Adkins see in Guly?" Keep them coming in to me at email@example.com. Dave will also have to contend with the Premier League's loudest PA system - ear plugs are advisable.
Polish keeper Artur Boruc makes his Southampton debut as Nigel Adkins looks to shore things up at the back.
Gabriel Sutton writes: "I'm already getting the impression it'll be the Saints home form to keep them in this league. Even though this isn't the sort of game Nigel Adkins will want to write off, I'm seeing a West Ham win - 2-0"
