Second chance of the game for Chelsea striker Nicolas Jackson but his shot is palmed away by Mark Flekken at his near post.

Southampton don't properly clear a Spurs corner and Djed Spence and Dejan Kulusevski have shots blocked.

Then Son Heung-min has a shot saved by the returning Alex McCarthy. Could be a long evening for the Saints.

Russell Martin has made plenty of changes in the Premier League which has not helped Southampton. He's still desperately trying to find the right mix of players.

Chelsea keeper Robert Sanchez rushes out of his box to beat Bryan Mbeumo to a long ball on the wing.

Joe Aribo catches James Maddison late. The Spurs man rolls around for a bit but he's OK. Just a free-kick, no card.

Yehor Yarmolyuk is making his third successive Premier League start for the first time this season.

The 20-year-old midfielder has long been considered one of the best young talents at Brentford and is now finally establishing himself under Thomas Frank.

This is another big test for the Ukrainian at Chelsea after positive performances against Aston Villa and Newcastle in recent weeks.

Good tackle from Jan Bednarek to stop Dejan Kulusevski mounting a dangerous counter-attack.

Thirty six seconds is the earliest goal Southampton have conceded in a Premier League game since Stoke goalkeeper Asmir Begovic scored after 13 seconds in November 2013.

This is Djed Spence's first ever Premier League start. He might get some more soon after that early assist.

Tottenham (36 seconds) have scored their earliest Premier League goal since January 2018, when Christian Eriksen scored after 11 seconds against Manchester United.

There were 36 seconds on the clock I believe when James Maddison bagged.

We are talking about Jed Spence starting the game. He's been in and out of this side. What a run and what a ball from him. It's a massive opportunity for him.

James Maddison still has to finish. It's brilliant from him. What a start from Spurs.

Early chance for Chelsea but Nicolas Jackson glances a header wide from Malo Gusto's cross.

Enzo Maresca and Thomas Frank were both full of praise for each other this week.

And Russell Martin and Ange Postecoglou both insist they will stick to their principles despite some shocking form.

We are under way at Stamford Bridge and St Mary's.

Enzo Maresca has been asked about the absence of defender Benoit Badiashile before kick-off.

He said: “For now, we don’t know how long he will be out for."

The Frenchman is understood to have been injured in Saturday's training session before this match at home to Brentford.

He was likely earmarked for this match given he didn't travel to face Astana in Kazakhstan on Thursday.

Sutton's prediction: 1-2

This should be a great game of football.

It is one for the purists really, because Southampton will play their defined style under Russell Martin and Ange Postecoglou's Tottenham will definitely do the same.

Both managers have been criticised recently and some of the stuff written and said about Postecoglou, after Spurs lost to Chelsea, was staggering, although it is the same after every defeat.

As I said on the Monday Night Club, on their day, Spurs are the best team to watch in the Premier League, but they are just patchy.

They should get over the line here though, because Southampton have bigger problems.

It looks like Saints are going to get relegated, but I hope they see the bigger picture when it comes to Martin.

For starters, he got them promoted, which wasn't an easy job. Keeping them up was always going to be even harder but, because Southampton have had a pretty recent spell of doing OK in the Premier League, their fans think they should be doing much better.

It was a similar story with Leicester City under Steve Cooper, where expectations were unrealistic. He got the sack but I hope Saints stick with Martin because, with a bit of patience, they could come back stronger.

Tottenham manager Ange Postecoglou says he loves "being in the middle of a storm" and intends to "double down" on his principles amid his team's poor run of form.

Spurs are winless in five games in all competitions, with Manchester City the only team they have beaten since early November.

"I am here, I am in for the fight," said Postecoglou. "I am in a fight, for sure. For better or worse I am not going anywhere at the moment because everything is still in my power and my responsibility.

"I still have a real desire to get us through this stage so that people see what is on the other side. My resolve and determination hasn't wavered one little bit.

"I love being in the middle of a storm when everyone doubts, because I know what it is on the other side if you get through it. My job is to get through it.

"That doesn't mean I'm inflexible and you don't make slight adjustments, but in tough times you double down on your principles because if you get through there's nothing to fear ahead of you."
