Match of the Day
If you missed it earlier on Facebook, here's the Match of the Day running order.
10:30 BST. BBC One. Don't miss it.
Southampton 1-0 West Brom
West Bromwich Albion
West Brom boss Tony Pulis speaking to Match of the Day about Sofiane Boufal's goal: "The viewers will see it and think it's a wonderful goal. He's going past five players, one or two you'd hope would do better. It's disappointing.
"Second half we changed it and had a lot more chances. We really had the best opportunity of the game - if we score there it's a different game.
"Second half our performance was much better and we made much more of a game of it."
"The game has changed. A few years ago he would have been stopped."

Less than two minutes in and Barcelona are ahead through Gerard Deulofeu.

Southampton 1-0 West Brom
Southampton
Southampton boss Mauricio Pellegrino speaking to Match of the Day: "It was a physical game, the weather conditions wasn't the best, but we put them under pressure. We created chances and scored at the end."
On Sofiane Boufal's wonder goal: "Sofiane has got ability to do it, we had to change at the end because they put five defenders. We made the right decision and got the victory for more confidence for the next game.
"I can say that we have got a group of players that most of them deserve to play, but the manager has to choose 11. Sofiane has to wait for his opportunity.
"They were pushing, but tried to play more simple and direct with good deliveries. They create problems, but we controlled well."

Hamza Darby: I've defended Pulis but this negative football is taking it's toll. Only 4 wins in 2017, it's hardly working either!
Fabian Crusoe: Pro's careers are short and to play so much of it without the ball is a crying shame. Pulis ball is cruel on all involved
The football isn't over tonight - it's top v bottom in Spain (Barcelona v Malaga) and first v second in Italy (Napoli v Inter Milan).
Southampton 1-0 West Brom
Southampton
Southampton goalscorer Sofiane Boufal on BT Sport: "My first Premier League goal of this season, yes, it's very special - the most important thing is we take three points - more important than my goal.
"I scored one in France I remember, but I am so happy with this goal. I am so hungry. The most important thing is to show the manager on the pitch I can play with this team."
That Boufal goal is not the only reason you'll want to watch Match of the Day tonight.
There have been goals all over the shop.

Southampton 1-0 West Brom
Sofiane Boufal has just suggested that was not even the best goal he's scored in his career.
I don't believe him.
Full quotes coming up.
Southampton 1-0 West Brom
I asked before the game whether Tony Pulis or Mauricio Pellegrino would be under pressure were they to lose today.
The Baggies are seven games without a win now. They have only won two in their last 18.
What do you make of that West Brom fans? Baggiesguy (below) is not impressed. Agree?
#bbcfootball
Matt McNicholas: Thank god. It's no more than Southampton deserve. Pulis is the death of football as we know it.
Baggiesguy: As an Albion fan I despair. These players are capable of attacking football. But the management won’t let them. Time for change
Sam Jamaa: Simply Bou-ti-fal (Sorry)
Don't aplogise Sam. I like it.
Southampton 1-0 West Brom
The Saints fans are posing for selfies with their players.
What relief.
It's their first win since 16 September and a first at St Mary's since the second game of the season.
Southampton 1-0 West Brom
All over!
By no means a classic but that goal from Sofiane Boufal deserved three points.
He's getting a rousing round of applause after the full-time whistle.

Kicked long from West Brom. Booted away by Lemina.
Now Southampton can break. Boufal. To Austin. Austin rounds the 'keeper... Post!
So close to a second goal. Just seconds remaining.
Southampton 1-0 West Brom
Tony Pulis is bouncing around on the touchline. His West Brom side just can't get the ball. This has been a very professional finish from the Saints.
Southampton 1-0 West Brom
Southampton are almost there. They have the ball and look intent on running the clock down.
Southampton 1-0 West Brom
That was Sofiane Boufal's his first goal in 23 Premier League games. Surely one of the best he's ever scored.
Can West Brom conjure up one last chance? We're into four minutes of added time.
Southampton 1-0 West Brom
That goal gets better and better every time you see it. Worth the wait Southampton fans?
Boufal's skill had two Baggies defenders clattering into each other and on their back side. Brilliant stuff.
To make matters worse for Tony Pulis his side are going to finish with 10 men. Having made all three subs, Craig Dawson is limping off.
