Another change for Manchester United - this time Ashley Young coming on for a hobbling Angel Di Maria. The ex-Villa winger is booed by the home supporters.

Robin van Persie has had a quiet night, but he bursts into life and almost levels the scores with a snap-shot which hits the inside of the post and somehow rolls to safety. The follow-up is blazed over the bar.

Who's got Saido Berahino in their fantasy football team? Good work. For those who haven't, it's that age-old quandary of wondering whether he'll stop scoring the minute you transfer him in.

Manchester United make a change - sending on Radamel Falcao for Juan Mata.

We apologise to those who voted on our great FA Cup goals earlier, but because of a technical issue the vote has been cancelled.

Ahmet: , externalWhere is RVP? Is he on the pitch? He has been DREADFUL. I think he is finished as a top striker.

Colin Reardon:, external Is RvP playing for #MUFC tonight?

Louis Strong: , externalHas RVP even touched the ball this half? Time for another tactical sub with Falcao, LVG?

Did anybody else notice Rafael screaming at Saido Berahino in a last-ditch attempt to put the striker off as he pulled the trigger? Not that it worked much...

Tom Holmes: , externalRafael all over the place, absolutely shambolic offside trap. Pitiful. But class personified from Berahino.

"You could get four articulated lorries and a jumbo jet between that Manchester United back four. He's bent it into the corner, a great finish but defensively there were huge gaps in that back four, with Rafael playing everyone onside."

Saido Berahino, what a striker! The West Brom youngster races on to a defence-splitting pass and outstrips Rafael for pace before opening up his body and slotting a fine finish from David De Gea. A finish Michael Owen would have been proud of. The Baggies are back in front.

The sweat is pouring off Marouane Fellaini. He's only been on for 20 minutes, although it must be hot underneath that barnet of his.

Fancy some stats? Of course you do...

• Marouane Fellaini failed to score with any of his 18 shots for Manchester United in the whole of 2013-14 (all comps), but he scored with his first in 2014-15.

• Fellaini's goal came just 2:35 minutes after coming on for Man Utd; the second fastest goal by a sub in the PL this season.

• Sergio Aguero's goal 23 seconds after coming on for Man City v Liverpool is the quickest.

Sandra Marsh: , externalAs a joint #MUFC and Chelsea fan I know about good man management. Moyes was a weight on Fellaini. Now he is gone he can shine

The home supporters are furious that the referee fails to see Rafael handling the ball when the Baggies would have been in. United surge up the other end and Adnan Januzaj wins a free-kick which is swept in by Angel Di Maria and headed clear by a Baggies defender. Getting spicy now.

"They are absolutely battering West Brom at the minute. United's fans can sense. It's attack after attack and great play from United."

Manchester United are flying forward at every opportunity now and Craig Gardner has to make a crucial interception in his own penalty area, before Andre Wisdom finds himself in the right place at the right time to clear Rafael's dangerous pass across the face of goal.

Joe in London: Fellaini 2.0 looks alright eh?

Wondering who runs the official West Brom Twitter account? Just look for the person with the reddest face inside The Hawthorns right about now.

Hang on a minute, Charles... I'm fairly certain Ed Woodward didn't sign a cheque for all that money just for a second-half leveller at West Brom.

Charles Kahanji: , external£27.5million transfer fee repaid.

Marouane Fellaini is playing as a striker since coming on and a cross from the left is just taken from his head before it has chance to ripple the onion bag. It's all United now.
