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.

"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!"

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.

"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.
