Matt in Kent: I've tuned in to watch Chelsea three times this season and they've lost each time, I'm an Arsenal fan, might tune in more often!

Kamran in Watford: Chelsea haven't even turned up today. Dreadful performance, would love to see West Brom score a couple more.

Kyle, Newcastle fan: Shocking decision not to send off Terry. Great to see the boring side getting beat No way back for them now. West Brom have been excellent all night.

This is like a classic away performance from West Brom - only at home.

Just seconds before their third goal, after a patient passing move, James Morrison had a rasping drive tipped over by Thibaut Courtois.

Jose Mourinho will be fuming.

"It's a lovely strike from Brunt but I think Courtois will be disappointed. Filipe Luis went out for the 2 v 1 corner but he didn't get any help. Jose Mourinho will be fuming, it was such a disorganised goal."

What is going on here?

Chris Brunt takes a quick corner on the left to James Morrison, he gets the ball back before cutting inside and drilling the ball home from outside the penalty area.

Thibaut Courtois should be keeping that out.

Chelsea keep pressing....

"It was brilliant from Remy, lovely feet, he wasn't quite set but he struck it sweetly. Myhill didn't move."

Chelsea are still dominating possession but West Brom are so well-organised, they don't look like hurting the Baggies.

Just as I say that, Loic Remy wriggles clear before shooting low against the post from 20 yards. It is going to take something like that to beat West Brom's defence tonight.

On Twitter:, external Joking apart re Terry and red, that decision could have an impact on Sunderland. Could have been no Fabregas and no Terry on Sunday.

Only four WBA players have scored Premier League hat-tricks: Lukaku, Tchoyi, Earnshaw & Odemwingie.

Saido Berahino needs just one more...

Andrews Tawiah: This looked like a game Chelsea were going to lose from start. So narrow with too many touches and passes.

Paul Collins: Chelsea on holiday, only reason to be behind against a team who made no attempt to even beat Newcastle recently.

Craig Gardner replaces Callum McManaman in West Brom's midfield. McManaman looks to be limping off.

Some news from League One - and a permanent deal for Tony Mowbray, who has agreed a two-year contract at Coventry City.

"Chelsea are conveying with their body language that they're not panicking. They haven't downed tools yet."

Diego Costa turns one way and then another inside the penalty area. He twists and turns so much he is left looking a little inside out himself as West Brom hack the ball clear.

Chelsea are two goals behind for only the third time in a Premier League game this season (also trailed by two vs Spurs and Newcastle).

Can they recover with just 10 men?

Ash Williams: That should've been a 2nd red for Chelsea.

Mike Thomas: You tell me why Terry didn't even get a yellow for that?

Mark Adamoulas: That should have been a red, in contrast to 1st half. Of course, two wrongs make a right... Poor eve to be a ref!

"I don't want to see anyone get sent off but it's a clear goalscoring opportunity. He's come straight through the side of Berahino and very late. It has to be a booking at the very least. Courtois will be disappointed - he gets a good strong hand on it and could have maybe turned it round the post."

I was the first to defend Cesc Fabregas after his red card in the first half but how didn't John Terry see red for that? The Chelsea skipper took Berahino out when he had just Thibaut Courtois to beat. To receive no card at all was just baffling.

Chelsea goalkeeper Thibaut Courtois howls in anguish as he gets a big hand on Saido Berahino's low penalty down to his right, but he can only parry it into the net. A huge task for Chelsea now.

John Terry cleans out Saido Berahino as the striker goes through on goal. Clear penalty but no card.
