Back under way in the West Midlands too.

Can Birmingham keep their unbeaten league start going?

Swansea have made a substitution at half-time, with winger Josh Ginnelly replacing wing-back Harrison Ashby.

It looks like a change of formation from 3-5-2 to 4-4-2 as head coach Michael Duff aims to correct things after a first half in which his side were dominated by Bristol City.

Southampton made two half-time changes.

Che Adams and Ryan Fraser are on.

Sam Edozie and Stuart Armstrong are off.

We are back under way at the Stadium of Light (Stadium of Darkness if you're a Southampton fan).

You would expect the Black Cats to put it in cruise control now.

Whilst Saints are trying to go uphill with a broken clutch and flat tyre.

Tim Miller: Southampton have made some shrewd loan signings but having lost Lavia and Ward-Prowse, we desperately needed to replace one of them in the deeper central midfield positions. And we haven't. We are going to be a light touch through the middle all season now!

Bristol City's fans are furious, booing referee Oliver Langford off the pitch half-time after he disallowed three goals for the visitors.

Two of them were for offside and another for what looked like quite a clear push in the back of a Swansea defender at a set-piece.

Bristol City have absolutely dominated that first half but somehow they trail to the Swans, whose only shot on target was their goal.

No goals in this one but the away side firmly on top so far.

A win for Phil Parkinson's men would move them level on points with seventh place.

This is fully deserved for Sunderland.

They do look a threat going forward.

Especially when you've got players like Pierre Ekwah, who's not afraid to pull the trigger.

The Lions lead at the break.

Kevin Nisbet's early free-kick beat John Ruddy on his side of the goal to put Gary Rowett's men in front.

Blues have responded well since but missed a great chance to level right on the half-time whistle when Scott Hogan saw his penalty saved by Matija Sarkic in the away goal.

Late drama at the end of the half!

Matija Sarkic is penalised for a foul on Keshi Anderson in the area but redeems himself with a save from Scott Hogan's penalty.

Liam Cullen's goal has the home side on course for a first league win of the season.

However, the away side have had much the better of it since the Swans took the lead inside the first 10 minutes and they'll be confident they can make that pressure tell sooner or later.

Nigel Pearson's men have actually had the ball in the net three times but had two ruled out for offside and the other for a foul.

Fourth time lucky?

One way traffic at the Stadium of Light.

Sunderland are dominating.

If they were in the gym they would be in the squat rack with the bar and a few 50kg plates on either end.

Southampton would be next to them trying to squat a toothpick.

Saints are nowhere in this game and have a mountain to climb.

Gavin Bazunu keeps Southampton in the game!

A terrific low save at the far post from a Sunderland free kick.

Full body stretch, the ball thumps him in the the gloves and he pushes it away.

Sunderland's Abdoullah Ba looking like Sonic the Hedgehog out there.

Working the nearside edge of the Southampton box with Ryan Manning tracking back before him, Ba whips out at least a dozen stepovers, before trying to squeeze past the Saints defender.

But he flops in the box and is booked for diving.

Southampton's Sekou Mara goes into the referee's notepad for a challenge on Sunderland's Jack Clarke from behind at midfield.

Looked a little soft to me.

10 minutes left in this first half. Is there another goal in it before the break?

Sunderland are finding the space around the pitch nicely and picking out players with long passes.

Bradley Dack pings a ball to Jack Clarke on the far side.

He glides over the grass with the ball at his feet and shoots a low stinger from outside the box, which is gathered neatly by Gavin Bazunu in the Saints goal.

Millwall are forced into an early change as skipper Sam Hutchinson is forced off with an injury.

Wes Harding, formerly a Birmingham player, is on in his place.

Bristol City have the ball in the net for the second time today and for the second time today the flag is up for offside.

Sam Bell the man frustrated this time.

Swansea are living on their nerves here.
