It's rolled short to Stuart Armstrong, he smacks it first time and a penalty has been given for handball against Kelechi Iheanacho!

Stuart Armstrong drives down the left and beats Timothy Castagne for pace. He uses his body to shield the ball as Castagne comes in hastily and wins a free-kick.

A chance for James Ward-Prowse to put a ball in. Can they get anything from it?

Another deep cross in from the right by Leicester but Luke Thomas is a long way out. His header is comfortable for Alex McCarthy.

Ayoze Perez' touch is loose then Wilfred Ndidi comes in late on Che Adams.

James Ward-Prowse wants a yellow - he's arguing it's the same challenge as Takumi Minamino's was on Luke Thomas a few moments ago which did warrant a card.

It will be wave after wave of attack from Leicester. Southampton will be ultra defensive.

Timothy Castagne and James Maddison play a one-two in the box but Takumi Minamino just squeezes out the space on the byline.

Luke Thomas curls in the free-kick but Alex McCarthy is out to gather it in. It's pumped up the field and possession is straight back with Leicester.

Going to be a long half.

Jonny Evans sends it long for Kelechi Iheanacho but Mohammed Salisu deals with it well.

Takumi Minamino is then booked for a late challenge on Luke Thomas.

Takumi Minamino's curling cross is deflected off the front man and it bounces a little awkwardly but Kasper Schmeichel just about stretches to gather it in.

Think we need some goals don't we?

Second half under way.

That change is made by Brendan Rodgers. Wesley Fofana is off. On comes Ayoze Perez for Leicester.

(Had to double check she wasn't meaning an acronym from Line of Duty at first)

My mum has just text me about VAR.

It's official. It's gone global. No escape from it now.

Brendan Rodgers was giving Ayoze Perez some instructions and pointing at areas on the pitch during that first half.

He was sent to warm up a few minutes before the whistle so it's likely he will come on. Leicester have been flat so far!

Only Arsenal (12) have received more Premier League red cards since Ralph Hasenhuttl's first game in charge than Southampton (9).

Southampton have had more red cards against Leicester (7) than against anyone else in the Premier League.

Jannik Vestergaard's first red card in 252 appearances in Europe's top five leagues.

The red card changed the game drastically. Southampton are frustrating Leicester. It was a sending off. It was a shocking tackle.

I think it will be a game that is won late on. Leicester will have to tire Southampton out because they are stuck in their shape.

It is difficult to break them down.

Southampton have held on with 10 men for well over half an hour so they will be pleased with that.

Brendan Rodgers will surely change things around at half time?

Timothy Castagne whips a ball in from the right but Kelech Iheanacho can't get any power on the header. It bounces off him and into the arms of Alex McCarthy.

Jan Bednarek sends a long free-kick into the box which comes off the top of Che Adams' head before Leicester get it away.
