Close again!

Another good move from West Ham sees Michail Antonio get down the left and chip a cross in for Jarrod Bowen to head over.

Willy Caballero - 40 years young - is drawn into action for the first time in Southampton's goal. He gets up to claw away a corner ahead of Kurt Zouma.

Mad Hatters, perhaps?

Luton Town had chances to put Chelsea under further pressure but now it's level. What a relief to the Champions League holders, who had been really struggling against The Hatters. Maybe Chelsea's night will calm down a bit now.

Norwich City

Dean Smith said Norwich fans and the club as a whole haven't been considered when it comes to fixture scheduling.

The Canaries face Liverpool in the FA Cup at 20:15 GMT, on Wednesday before hosting Brentford in the Premier League at 15:00 on Saturday.

Should Norwich or Chelsea progress in the FA Cup, their league match scheduled for Saturday ,19 March will be brought forward , externalto Thursday, 10 March - three days before Smith's side are due to play Leeds.

When asked whether fans have been put at the heart of these decisions, Smith said: "They certainly haven’t. I don’t think us as a football team have been either.

"It’s two big games with teams around us in Brentford and Leeds, and why it can’t be on the Tuesday or Wednesday heaven knows why. The Premier League fixture makers are the only ones who know why.

"I know it’s a Champions League night but the precedent was set the week before when there was a Champions League night and Burnley played Tottenham.

"It’s not ideal at all. Heaven knows what time the (Liverpool) game finishes if it goes to extra-time and penalties. We just have to deal with it unfortunately. The fixture calendar is not ideal but it is what it is".

Talk about composure, quality, this finish is certainly that - it is a little bit fortunate the way the ball ends up with Saul, but take nothing away from the finish. He anticipates where the ball is going to come out. It is out of nowhere really.

Jack Stephens to the rescue again.

The Saints defender is somewhat at fault as he steps up seeking offside but allows Michail Antonio to break. Stephens gets back, though, to tackle.

Both of the Saints wide players are moving centrally. It's your classic 4-2-2-2.

One of those middle men - Will Smallbone - has a pop at goal from the edge of the box but a diving West Ham defender blocks.

Chelsea just cannot deal with crosses into the box from Luton.

This time defender Dan Potts meets a header but it is straight at Kepa Arrizabalaga.

Rachel T: If that’s a ruptured Achilles for Steer I feel for him - done both of mine, separately, and it’s a killer injury to recover from.

Ouch! Fingers crossed it's not then.

As you'd expect with the changes made to the respective sides, West Ham (two) have settled quicker than Southampton (nine).

First effort on goal for Chelsea are the outcast Saul Niguez sneaks in at the back post but heads straight at Harry Isted.

Wonderful move from West Ham, slick passing. It comes through to Soucek but he scuffs at it. It was a great opportunity.

Southampton can't cope with Lanzini, he's playing through the lines.

West Ham go close!

A lovely sweeping move sees them pick through Southampton. A couple of deflections then set up Tomas Soucek for a shot at goal that he tamely puts wide.

Good start to this game.

Liverpool's goalkeepers have just been out to warm up and Caoimhin Kelleher has just got a brilliant reception from those already in the stands following his League Cup final heroics.

There was also a big cheer when the announcer just revealed that Chelsea are losing...

Chelsea have not been creative at all, they have not got into wide areas.

West Ham get a lucky ricochet to set them charging away into Saints territory. But Manuel Lanzini's cross with the outside of his boot comes off Jarrod Bowen and goes behind for a goal-kick. What a waste.

20 minutes gone, zero shots from Chelsea.

Shaken.

Have the players got blocks of Toblerone on their feet? Craig Dawson now slices an awful pass straight out of play.
