West Ham ended four-game winless run with victory over Spurs last week
Southampton secured Premier League survival last week
West Ham 0-0 Southampton
West Ham switched off at the back and allowed Mohamed Elyounoussi in on goal.
A slick ball over the defence falls to the Southampton number 11, he controls it beautifully to bring it onto his right foot, but unfortunately, his subsequent shot wasn't quite so beautiful, going well wide of Fabianski's goal.
I've heard a little rumour that some West Ham fans will be leaving today's game early in order to leg it over to Wembley to support the Hammers in the Women's FA Cup Final.
They play Manchester City at 17:30 BST, and it's live on BBC One.
Attending two football games in one day - a dream Saturday!

It's a chance for Grady Diangana again. He plays the ball to Marko Arnautovic, who feeds it back in a nice one-two, but Diangana's effort on goal is deflected over.
West Ham 0-0 Southampton
West Ham starting to get back into this one though, but they won't get very far with shots like the one Grady Diangana just unleashed.
He picks the ball up in the middle of the Saints half and goes for goal from way, way out. No problem at all for Fraser Forster.
West Ham 0-0 Southampton
Early chance for the Saints and for Stuart Armstrong.
Danny Ings, on the edge of the box, plays a neat ball through to Armstrong as he sprints into the area, but his shot drifts just high of Lukasz Fabianski's goal.
West Ham 0-0 Southampton
It's Southampton piling on the early pressure so far and captain Pierre-Emile Hojbjerg has demonstrated his side's intent earlier on, clattering into Pedro Obiang as both jumped for a header.
West Ham 0-0 Southampton
Everyone loves some head-to-head facts and figures, right?

The teams are out of the tunnel and those bubbles are blowing.
It looks like a lovely day in London, though Twitter told me it was snowing in the capital earlier! Bonkers.

Manuel Pellegrini has called this a transition season for West Ham, but it's still one in which they can finish in the top half of the table - something they haven't managed in either of the last two campaigns.
One of the major frustrations for Pellegrini will be that the Hammers have shown they can perform against the big guns, but have been hit and miss when facing teams lower down the table.
Southampton arrive fresh from securing Premier League safety after an impressive haul of 29 points from 21 games since Ralph Hasenhuttl took over.
It's not just results that have picked up under Hasenhuttl either, with the Saints good to watch as well. Their fans can be optimistic about next season.
