Full-time: Southampton 0-2 Chelsea
Antonio Conte's Blue boys go marching on, winning in impressive fashion on the south coast, despite failing to scale the peaks of last week. Still, I'm sure the Italian won't mind too much.
Until next time, folks.
Three minutes of time being added.
Another change for the away side: Diego Costa makes way for Michy Batshuayi for the last few minutes. The Blues are ticking off the seconds.
Antonio Conte is looking to sure up this result for the Blues now. Victor Moses gets a well deserved ovation from the Chelsea fans, as well as a big hug from his manager.
Moses comes close to adding a third goal for Chelsea, cutting in from the right side and unleashing a powerful effort with his left peg. That would've been a good reward for his impressive display this afternoon.
And then seconds later, Saints have the ball in the net - but only after Charlie Austin is correctly flagged offside.
Ten minutes left at St Mary's, then. Time for a comeback from the Saints, or will Chelsea coast home?
Bertrand and Tadic come off and McQueen and Højbjerg come on. Chelsea have made a change of their own, too.
And then, out of nowhere, a Davis header from distanced is deflected up into the air and onto the crossbar with Courtois beaten. Well, that moment took everyone by surprise - and will, perhaps, act as a wake-up call for the Blues.
Davis brings Pedro down and Conte is incensed that the Saints midfielder has not been handed a yellow card.
On second viewing, however, the Spanish winger appeared to be very willing to go to ground. Good call by the ref on this occasion.
Chelsea's latest counter-attack sees Hazard jink his way infield and get off a low, right-footed effort that is well stopped by the keeper. Good from the Belgian, though, who has continued his fine recent form today.
And to underline that point...
Charlie Austin heads over a cross from the left side and Southampton's search for a goal goes on. There's a distinct gulf in class between Chelsea's forwards, who carry a real cutting edge, and those of the Saints.
Southampton's threat has really dissipated in this second-half. They've not really looked like scoring since the break.
A huge goalmouth scramble sees Hazard, Costa and then Pedro all fluff chances to shoot at goal and then somehow - I don't know how - it remains at 2-0.
A goal appeared to be a certainty, there.
Boufal replaces Clasie for the Saints - but I fear it might be too little, too late from their viewpoint. Less than 30 minutes to go at St Mary's.
And now he's fluffed a MUCH more straight forward chance, blazing over a cross from the right flank. Oh well, you can't score 'em all.
GOAL: Southampton 0-2 Chelsea (Costa)
Diego Costa, take a bow! The in-form Spaniard has found the net with a brilliant curling effort from outside the box. Collecting the ball from the inside-left position and finding a pin-point finish with his right foot.
Chelsea really are starting to look a threat on the break, with Alonso and Moses being encouraged to get forward at every chance.
The Saints, I fancy, might need to run the risk of letting them go free in the hope of catching the attack-minded duo upfield.
Watching Antonio Conte on the touchline is exhausting in itself. The Italian is up on his feet, constantly ranting and raving at his players. I'm not sure I've ever seen such an animated boss.
Jose Fonte comes to Saints' rescue, making a last-ditch block from an Alonso cross that stops Hazard from tapping in a second from close range. That was brilliant from the centre-back and underlines why he is rated so highly.
Saints start the half on the front foot, before Hazard leads Chelsea from one end to the other and wins a corner. It comes to nothing, though, and the hosts are able to clear.
The players are back out at St Mary's and we're under way on the south coast.
Half-time: Southampton 0-1 Chelsea
The Blues lead at the break thanks to Eden Hazard, even though the Saints have largely dominated. Back for more in a bit, folks.
Diego Costa misses a potentially match-winning opening! He latches onto a well-timed through-pass from Nemanja Matic, races into the box and shoots low. But his powerful effort is save by the feet of Fraser Forster.
That really was a good chance for Antonio Conte's men.
