John Murray was right, that is the section where a lot of the players' families sit.

Probably on X: Very disturbing scenes at The Hawthorns, harking back to the darkest days of English football. Fans fighting each other and with police. If it's not sorted soon, the game should be abandoned and both clubs should be kicked out of the competition.

There are loads of police and stewards in the far corner trying to get the situation under control.

Immediately after Matheus Cunha's goal, missiles were thrown from into and out of the visitors section.

The fighting started at the other end of the stadium. A fan has been taken past me by police.

There are huge numbers of police in the far corner trying to restore order.

Kyle Bartley has come out with a child in his arms and I think that must be where the families are sat. That is why many of the West Brom players ran over to that corner. My assumption is that is where the West Brom families are.

Watford make six changes to the side who drew 1-1 with Bristol City last weekend.

There’s a first start of the season for Mattie Pollock in defence.

Jamal Lewis makes his first start since recovering from injury.

Watford XI: Bachmann, Sierralta, Hoedt, Lewis, Kone, Pollock, Chakvetadze, Asprilla, Bayo, Martins, Andrews.

Southampton manager Russell Martin makes nine changes to the side who won 3-1 against Swansea last weekend.

Seventeen-year-old English midfielder Tyler Dibling makes his first senior start. The youngster signed a new contract last December, keeping him at the club until 2026.

Joe Rothwell makes his first start for the club after signing on loan from Bournemouth.

Southampton XI: Lumley, Holgate, Stephens, Harwood-Bellis, Meghoma, Charles, Rothwell, Dibling, Alcaraz, Mara, Adams.

Subs: McCarthy, Walker-Peters, Manning, Bednarek, Smallbone, S Armstrong, Fraser, Amo-Ameyaw, A Armstrong.

West Brom defender Kyle Bartley has his child in his arms as he looks at all the trouble.

Genuinely shocking scenes here.

The game has been suspended for now. The fighting is still going on.

West Brom's players are off the pitch now as well. This is really like the bad old days.

Wolves' players are walking down the tunnel now. A West Brom fan runs onto the pitch with stewards taking him away.

I think some Wolves fans have celebrated in the home end and the West Brom fans have reacted to it.

The ITV commentators say there are fights in two different sections of the ground, with police having to get involved in each one.

It's been three or four minutes now.

The police are heavily involved here and you can see fans throwing objects. Really bad to see this.

A huge fight has broken out in the stands and the referee won't let the players kick-off until it's sorted.

They are not easy finishes. Cunha's first touch takes him away from goal but he puts it through his legs.

West Brom midfielder John Swift pings a sweetly hit effort just over the bar from 20 yards. How many more chances will the Baggies have?

It's a good job there is no VAR in this game.

Slowed down, I don't think that incident involving Kyle Bartley would have looked good at all.

Clearly there was nothing in his mind other than stopping Matheus Cunha. It was high.

I am not advocating players to get sent off and in an atmosphere like this, it is part of the hurly-burly but I don't think he would have survived Stockley Park's involvement.

Wolves have just been better today. West Brom have not unsettled them, they've played right into their hands.
