- FT: Rondon goal earns win for West Brom
- Man Utd lose ground on top four
- United's Mata sent off for second yellow card
- Germany Women v England Women (kick-off 22:30)
Manchester United manager Louis van Gaal speaks to Sky Sports: "We played with 10 against 11 and this is the fifth match in 14 days I believe so it is very difficult. I think that's the reason why we lost this game.
"The only chance was the goal so what can I say, it is a pity."
How many points do you now need to fight for the top four? "27 points."
Manchester United manager Louis van Gaal speaks to BBC Sport: "What can I say when you send off a player like Mata. I have asked him if it's his first red card and he said yes. When you do that you give the first and second yellow within five minutes. You can do it according the rules but I think the referee has to know the person doing it. I don't think Mata has ever had bad tackles and something like that.
"You know the first one is a stupid yellow card and then you have to be aware the referee can give a second yellow card. A referee has to decide within one second but when you know the player, Mata never hurts a player.
"When you have to play 75 minutes with 10 players. I don't think we were so uncomfortable. We had several chances to score so it's always more difficult when you play 10 against 11. It's always very difficult for a team to play against 11.
"The loss is a big blow because it was not necessary. When you see the first half it was not necessary I think."
West Brom manager Tony Pulis speaks to Sky Sports: "The three points and them going down to 10 affected the game. We watched Liverpool go down to 10 before this game and they won 2-1. You're never comfortable against top teams with pace up front and they have pace. Once we got the goal we kind of settled down.
"Second half we were definitely off the pace a bit but the goal was a smashing finish [by Rondon]. It has taken him time to settle in and he has had ups and downs but they love him to death here.
"At the start of the season before the nonsense with Saido I was looking forward to them playing together. Since Saido has come back in the two of them have looked really lively together and we look a threat.
"The most important thing is the next game, as you've seen this year, results have been off the radar. Let's get 40 points, I think that's definitely safe."
We have just come across this gem of an image courtesy of Divock Origi.
It seems footballers these days can't go anywhere without a bottle of red ketchup. Kolo Toure has it covered if you look closely. Priorities.
Manchester United midfielder Michael Carrick: "It's a set back. We wanted to carry on the form and results we have shown of late so it's very disappointing. Losing a man like we did makes it even more difficult.
"It changed the game because you have one less man in attacking areas which affected us on the break especially. They were not causing us many problems but took their chance."
On the top four challenge: "It's not out of sight. We just need to get back to winning ways. It's easy to say. We have big cup games coming up and we need to be ready to them."
Yanis Gbl: Excluding De Gea, Smalling, Martial, all those United players were shocking and don't deserve to even wear the shirt.
Atticus Montreal: Wenger's timeless hold on 4th place seems set to continue thanks to Man U dropping points.
Jon Batham: With the run in United have left they will be lucky to finish top half now never mind top four or top six.
Not only do Manchester United miss the chance to overtake West Ham, they slip back into the clutchs of Liverpool after the Reds claimed a third successive win today.
West Brom, meanwhile, overtake Everton and Watford and are within spitting distance of the top half now.
West Brom midfielder Darren Fletcher speaks to Sky Sports: "First and foremost it takes us to 39 points, one more from 40 and then we will look to keep going. I thought to a man our team performance all round the pitch was fantastic."
On the red card: "It was the referees decision, I tried to take a quick free kick and get blocked and then tried to start a counter attack and got tripped. It's the refs decision.
"I thought we looked flat when they went to 10 but the advantage of 11 v 10 seemed to get us through in the end.
"When you're playing against your old club you are desperate to win. You hope United have great success but my first thought now is West Brom. Can we reach that magic 50 points that West Brom have never had before?"
It's all over. The Baggies have done it! Three wins from four for Tony Pulis's side, and they are surely safe now.
As for Manchester United, their mini-resurgence comes to a juddering halt, and their ambitions of making the top four are dealt a body-blow.
Pumped into the West Brom area...Schneiderlin rises for it...the ball falls to 18-year-old Timothy Fosu-Mensah...he winds up...
He shanks it horribly.
Depay passes it straight to Olsson. Not happening for United...
Tony Pulis barks his instructions on the touchline. United haven't created very much at all since going behind...
West Brom sitting deep in two banks of four, United camped in the opposition half, trying to find a way through. Four added minutes for them to do so...
Former Leicester City midfielder on BBC Radio 5 Live
"It's always such a big moment when you beat Manchester United, no matter what place they are in the league.
"When you are sitting in that changing room after the game its such a great feeling. For these players out there who haven't beaten them before, they are really close now this is a huge final few minutes."
A change that signals West Brom's defensive intent. Sandro, who doesn't have as much hair as he once did, replaces Saido Berahino.
Albion win a corner and take it short. Eventually the ball is worked to Claudio Yacob, who carelessly lofts it into the hands of David de Gea.
Manchester United have had 70% possession in the past 10 minutes. But they haven't been able to create any clear-cut chances with it. This is a very well-drilled West Brom defence and they're quite content to let United have the ball, backing their ability to repel any attacks by the ten men.
Fresh legs in the United defence, Timothy Fosu-Mensah replaces Matteo Darmian.
Tony Pulis has only had one managerial victory against Manchester United in 13 attempts. He's about 10 minutes away from a second...
Fayaz Adam: United's defensive line and shape is shocking. Blind has no clue whatsoever how to play that position! Always out of position! #'bbcfootball
Shohidur Rahman: Playing with 10 men for so long has killed us #bbcfootball
Ricky Everett: Mike Dean has cost us a chance at top 4 finish; will he have any reprimand? Of course not #BBCFootball

Whipped in by Depay, Olsson hacks clear.
Instant impact from Depay! Nice feet on the left flank and Craig Gardner chops his legs. Promising free-kick...
It's Marcus Rashford who departs. Not his day today. On comes Depay.
Memphis Depay is being readied on the touchline. Roll of the dice...
This, by the way, is Sebastien Pocognoli's first league appearance of the season and it's taken him 12 minutes to notch an assist. James McClean is on for Sessegnon.
Former Leicester City midfielder on BBC Radio 5 Live
"There you go! Someone needed to take a chance and do something different. That's the first time United have switched off defensively.
"What a ball in and what a first touch from Rondon. A superb shot into the bottom corner and David de Gea had no chance.
"They had a go, got a goal, and that's exactly what this Hawthorns crowd want to see!"
West Brom make the man advantage count! The Baggies work Sebastien Pocognoli into all sorts of space on the left and he whips in a glorious first-time cross. Rondon, ice in his veins, takes a good first touch and buries the finish. West Brom heading for certain safety, but a blow to United's top-four hopes.
Now it's West Brom who are starting to commit more players forward and looking to turn the screw of their numerical advantage. Sebastien Pocognoli canters up the left flank but Marcus Rashford, who has been diligent in defence, makes a good tackle.
Hang on - I thought it was Manchester United who were down to 10 men?! It is? You wouldn't think it having watched these past five minutes.
The Red Devils are virtually living in Albion's backyard. Tony Pulis might well need to call Sandwell Council's bailiffs to evict their unwanted visitors if this carries on.
Chance! Sessegnon whips in a great low cross which Saido Berahino meets with the outside of his boot on the edge of the area, but the ball goes just wide of the post.
Straight into the wall from Herrera, to the sound of a thousand stifled screams in pubs and living-rooms up and down the country.
Now then! Anthony Martial does brilliantly to latch onto a long punt downfield, he nods it in front cleverly and Jonas Olsson hacks him down. Mike Dean pulls out a yellow - there were men covering, just about...
Some holes in Sandro's conspiracy theory...
Joel: Sorry to spoil the conspiracy but Coquelin also had two yellows and definitely doesn't start with M!
Mr Anderson: Sorry Sandro you are forgetting Coquelin who's name begins with a C.
Matt in York: Francis Coquelin begins with an M? Is it silent?
Change for West Brom. Craig Dawson off, and Belgium international Sebastien Pocognoli, who has barely played this season, is on. He'll play left-back, James Chester shifts to right-back.
This is a good spell from Manchester United. Jesse Lingard cuts in from the left and comes over all Harry Kane, firing a curling shot just over the bar.
Former Leicester City midfielder on BBC Radio 5 Live
"Neither keeper was tested at all in the first-half. Just one shot for either side. From United's point of view with 10 men they defended well.
"They need to just try and get the ball up to Martial. He's got the pace to cause lots of problems for the West Brom defence.
"As for West Brom, they've not changed since Mata went off. All they need to do is try and play a bit more expansively and see if they can get the win."
Close! Anthony Martial does brilliantly to wriggle his way down the byline on the left side, and his falls to Marcus Rashford, whose low shot is deflected narrowly wide.
West Brom look to strike quickly as Manchester United retreat from an attack of their own, but Matteo Darmian does really well to get back and make a challenge on Sessegnon.
