Enjoy the games tonight and we'll see you again tomorrow.

For one last time (well, on this page anyway), this is what England and Wales need to secure a place in the knockout stages.

England

• England will go through regardless if they avoid a four-goal defeat by Wales.
• They'll also finish top of Group B if Iran and the USA draw and they don't lose to Wales by four or more goals.
• If England draw against Wales and Iran beat the USA, Iran top the group and England finish second.
• If England draw to Wales and the USA beat Iran by at least four goals, the USA will finish top of the group, with England in second.
• If England lose to Wales and the USA beat Iran, USA finish top of the group and England qualify second.

Wales

• Wales must beat England and hope for a draw between the United States and Iran.
• If USA or Iran win, Wales will need to beat England by four or more goals to finish second ahead of them.

Round of 16 matches

• Saturday, 15:00 GMT - Netherlands v Runners-up Group B
• Sunday, 19:00 - Winners Group B v Senegal

Wales must beat England and hope Iran and the USA draw to go through. If the other game is not a draw, Wales must beat England by at least four goals.

“I hope the boys do us proud,” one fan said before the match at Qatar’s Ahmad Bin Ali Stadium.

"Let's get a 4-0 result tonight and that will be fantastic," another said.

This is the last pub in England.

It’s in Saltney on the outskirts of Chester - it’s a town that’s divided by the Welsh border which runs along a road called Boundary Lane just next to the Brewery Arms.

It’s the most urbanised part of the England/Wales border.

Despite that, the landlord Danny Thomas told us the pub is “England all the way”.

He’s not expecting any Welsh fans to come in tonight – at all.

We're bringing you all the action. Here's how you can tune into tonight's Group B games:

Wales v England - Watch build-up from 18:00 on BBC One and BBC iPlayer. You can also listen from 17:30 on BBC Radio 5 Live or keep up with all the action on our live text page here.

Preston, a nine-year-old a pupil at Llangyfelach Primary School in Swansea, took the positive view of Wales ahead of the team's key World Cup clash with England.

Wales must win to stand any chance of progressing, and hope the USA v Iran game ends in a draw.

After missing out on football's biggest tournament since 1958, Preston told BBC Breakfast that the team had already "overcome 64 years".

This is how Group A finished after Senegal beat Ecuador and the Netherlands defeated Qatar.

What does that mean for Wales v England and Iran v USA tonight in Group B?

Whichever team tops the group would face Senegal in the last 16.

The team that finishes second will come up against Group A winners the Netherlands.

Wales faced 21 shots in their 2-0 defeat against Iran, the third time in their last eight games they’ve faced 20+ shots, as many as in their previous 62 games combined.

The last time they faced England at a major tournament, the Three Lions had exactly 20 shots in a 2-1 win at Euro 2016.

The Ahmad Bin Ali Stadium is starting to feel like a home from home for Wales, who are playing all three of their World Cup group games here.

Not that they've particularly taken to the place so far, drawing against the USA and losing to Iran before tonight's match against England.

The venue is hosting six group games and one second-round tie in total, and you can see the first signs of a bit of wear on the pitch.

The Netherlands and Senegal are through!

The Dutch await the runners-up of Group B (England, Iran, USA, Wales) while Senegal will face the winners.

Now it's over to Group B! England are on the verge of reaching the knockout stage, but Wales face an uphill battle in their quest to make the last 16.

So what do the home nations need to secure a place? Let's have another look now that Group A is done and dusted.

England

• England will go through regardless if they avoid a four-goal defeat by Wales.
• They'll also finish top of Group B if Iran and the USA draw and they don't lose to Wales by four or more goals.
• If England draw against Wales and Iran beat the USA, Iran top the group and England finish second.
• If England draw to Wales and the USA beat Iran by at least four goals, the USA will finish top of the group, with England in second.
• If England lose to Wales and the USA beat Iran, USA finish top of the group and England qualify second.

Wales

• Wales must beat England and hope for a draw between the United States and Iran.
• If USA or Iran win, Wales will need to beat England by four or more goals to finish second ahead of them.

Round of 16 matches

Wales fan and BBC Radio 5 Live's Elis James has been speaking to Kelly Cates about his hopes for tonight's game: "I was desperately hoping we would get out of the group but personally, I don’t think it is going to happen.

"Who knows what will happen tonight?

"No matter what happens tonight, we will always have that penalty which seeing us score, it was just it was like when Gareth Bale scored against Slovakia in the first game of 2016.

"Once you have seen a goal at a major tournament after having failed to qualify for so long, they are just really special.

"Whatever happens you can't be too angry or despondent because we waited so long for this and you can’t question any of the player’s commitment."

Gary will be working on tonight's match for BBC Radio 5 Live, and he's arrived nice and early.

Driving through Cardiff earlier and a steady flow of bucket hats were making their way to the pubs.

Now in Wales’ second city, Swansea, and the excitement is slowly increasing.

Two in three are wearing red. The red wall is building.

2,300 is the max capacity at the fanzine here which is sold out, but there is a whiff of apprehension in the air... nobody wanted a must win game against England today.

Two young men (who shall remain anonymous as they have come earlier than they told their wives) are “buzzing but not optimistic”.

They take a narrow loss.... but preferably a narrow victory ahead of a telling off at home.

Face paint is an essential part of a World Cup fan's kit and the England supporters arriving at the Ahmad Bin Ali Stadium are getting primed and ready for tonight's game against Wales.

However, the chap above will have to sit for a few more hours to match the painted greatness of the Senegal fans, who have looked like a work of art in the stands at each of their group games so far.

Hold on just a minute!

Senegal have retaken the lead!

As it stands, the winners of Group B (England, Iran, USA, Wales) will face Senegal. The second-placed team in Group B are certain for a date with the Dutch.
