FULL TIME: West Brom 2-3 Chelsea

Yacob launches one final ball into the box but Courtois plucks it out of the air to ease the pressure on his side. That should be that.

Five minutes of time added on at the Hawthorns.

Gnabry is trying really hard to upset Chelsea here. He dances past a challenge on the edge of the box and tries his luck from 25 yards out, but Courtois can save easily. Moments later down the other end, Hazard jinks his way into the from the left but drags his shot across goal.

Perdro's debut is over, and Mourinho is issuing a lockdown with John Obi Mikel coming onto replace him.

Serge Gnabry, on loan from Arsenal, looks to make an instant impact having come off the bench, but gets a little over excited and whacks a woeful shot on target into the stands.

West Brom close again! McManaman twists Ivanovic inside out, leaving him on his backside inside the box and tries to curl one into the far corner. He's inches away however, and perhaps someone in a West Brom shirt should have been gambling on that,

BANTER UPDATE: Chelsea's medical team is on the pitch to tend to the fallen Ivanovic. You're getting sacked in the morning etc etc

Rondon swivels and smashes a volley through a crowd of players but it veers just wide.

Matic concedes another foul after a silly push on Rondon. The Serbian, whose already booked too, has had a fairly awful afternoon.

Ooof, Chelsea so close to a fourth! Pedro whips a delicious ball across from the right and Costa connects with a brilliant half volley from a terribly difficult angle, but can only drill his effort wide.

Comeback on?! West Brom pull another back through Morrison, who connects with a brilliant backwards header from an outstanding cross from McManaman. Courtois is rooted to the spot as the ball clips the underside of the bar and goes on.

Tony Pulis has also thrown on Rickie Lambert, replacing James McClean.

Goal! West Brom 2-3 Chelsea (James Morrison)

Costa wins a clever free kick about 25 yards out from goal. Whose good at free kicks at Chelsea these days? Matic takes this one, anyway, but Myhill makes a comfortable save.

Terry takes his sweet time leaving the pitch, whipping his shin pads off in protest. Mourinho acts quickly and brings on Cahill for Willian to fill the void at the back. Rondo's free kick is deflected out for a corner but Chelsea clear.

Terry is gone! He's left in a race with Rondon to a loose ball and hauls down the West Brom forward on the edge of the box. Rondon was the last man and despite the protests, Chelsea's skipper is off!

RED CARD - John Terry

And we are back underway at the Hawthorns, no changes for either side.

HALF TIME: West Brom 1-3 Chelsea

Chelsea's two goal lead is restored. Fabregas dinks a ball over the top and Costa does well to hold off McAuley and knock the ball down for Azpilicueta, who has burst onto the edge of the box from absolutely nowhere. The Spaniard gets a deft touch on the ball and guides it into the bottom corner with Myhill rooted to the spot.

Goal! West Brom 1-3 Chelsea (Cesar Azpilicueta)

Oh Willian. More brilliance from Pedro as he races onto a poor header, rides one challenge as he jinks his way into the box before teeing up the Brazilian for a simple tap in. That he sends wide. Awful attempt.

West Brom move the ball around nicely, working it from right to left but McClean's delivery is plucked out of the air by Courtois. He launches the ball up for a counter but Willian wastes it with a rubbish shot from range.

McClean is booked for a silly challenge on Pedro. Chelsea have the free kick, but it is a bit of a waste.

A Zouma slip invites West Brom forward and despite making a hash of their first attempt to counter, Chelsea give the ball back to them for another ago. It's wonderful from Solomon Rondon, who keeps the ball in play brilliantly by hooking a deep cross from the left back into box where Morrison charges onto the loose ball to drill home.

Goal! West Brom 1-2 Chelsea (James Morrison)

A rapid counter from Chelsea gives them a two goal lead. John Terry nutts away a West Brom counter and Willian leads the counter, threading through a great ball for Pedro whose popped up on the right of goal. It's either a shot or a cross from the Spaniard across the face of goal but Costa is alive to it and sticks a boot out to tap it home.

Goal! West Brom 0-2 Chelsea (Diego Costa)

The corner falls to Fabregas who dinks a delicate ball over the top for one of his teammates. Matic and Costa run straight into each other however, in proper cartoon fashion.

Darren Fletcher's poor pass is cut out by Hazard who advances menacingly towards goal with West Brom short of numbers. He shifts the ball wide to Costa who settles for a corner.

Chelsea have taken control of this contest since that goal went in. Solomon Rondon hasn't seen a whole lot of the ball yet but he's doing his best to put Chelsea's backline under pressure, chasing down John Terry at every opportunity in particular.

Pedro has a goal on his debut! Or his it an own goal? Chelsea don't care. The Spaniard advances and plays a neat one two with Hazard before bursting into the box. He pokes a shot on goal that at takes at least one deflection on it's way through, beating Mhyill at the near post.

Goal! West Brom 0-1 Chelsea (Pedro)

West Brom still looking dangerous after that miss. McManaman scampers down the right again and draws a foul from Azpilicueta. Morrison swings a brilliant free kick into the box that McAuley rises to meet, but he can't keep his header down.

Matic is having a bit of a 'mare this afternoon. Morrison drops a shoulder and easily skips past the Serbian, who again sticks a lazy leg across to trip the West Brom midfielder. In the referee's book he goes.

Why didn't Chris Brunt take that? Reall,y I'd like to know. Decent stop from Courtois anyway, who dived to the left but managed to keep Morrison's effort out with his legs.

Saved! James Morrison takes responsibility for the spot kick and sends it straight down the middle, but Courtois gets a leg to it and keeps it out!

West Brom have a penalty! Nemanja Matic clumsily steps across McManaman, tripping the winger and it's an easy decision for the referee.

PENALTY - West Brom

Just a few minutes until kick off now with both sides making their way out onto the pitch.

As you can probably expect, Tottenham's efforts to sign Saido Berahino are the reason for the striker's absence from the West Brom squad today. And Tony Pulis is not happy with it all. He told Sky Sports:

It's absolutely ridiculous we are talking about something outside football. If you close the transfer window before the season starts, everybody can concentrate on football. A lot of clubs get affected during the window and we are not talking about football - which is down to the system."

Last week West Brom chairman Jeremy Peace released a statement revealing the club had rejected a bid from Tottenham for Saido Berahino, warning the north Londoners selling the striker was not on their agenda.

Today, the 22-year-old sits out completely, with Tony Pulis likely to be concerned about the youngster's frame of mind amid the ongoing speculation.

His omission allows Solomon Rondon to come in however, supported by both Callum McManaman and James McClean who come in to start on the flanks.

There's no hanging around from Jose Mourinho, Pedro comes straight into his first team this afternoon, taking up a spot on the right wing. With Eden Hazard out on the left, Chelsea have truly terrifying options on both flanks since the days of Arjen Robben and Damien Duff tormenting full backs.

Gary Cahill's poor start to the season has cost him his spot in the starting XI with Kurt Zouma stepping in alongside John Terry.

Burkina Faso winger Bertrand Traore, who won a worm permit this summer, is in line to make his debut at the Hawthorns, if he can make it off the bench.

Confirmed: Saido Berahino is left out completely by Tony Pulis today. Record signing Solomon Rondon comes into lead the line.

West Brom team to face Chelsea: Myhill, Dawson, McAuley, Olsson, Brunt, McManaman, Morrison, Fletcher (c), Yacob, McClean, Rondon

Subs: Rose, Chester, Lescott, Gardner, Gnabry, Anichebe, Lambert

Confirmed: Pedro makes his debut for Chelsea this afternoon, coming in on the right of an attacking three with Willian moving inside. Bertrand Traore makes the bench.

Chelsea team to face West Brom: Courtois; Ivanovic, Zouma, Terry (c), Azpilicueta; Matic, Fabregas; Pedro, Willian, Hazard; Diego Costa

Subs: Begovic, Cahill, Mikel, Loftus-Cheek, Traore, Remy, Falcao.

This week Jose Mourinho was extremely critical of his side that has taken just one point from a possible six while extolling the virtues of his new signing Pedro. Can we expect to see the former Barcelona winger in action today?

This week we trained better than ever. Why? Because we are not happy. I'm not happy with the results, the players are not happy. We want to do better and the only way is to work well.

"This week we got a very good young left-back and we got one of the best attacking players in the world. Pedro is a player we like a lot and we are happy to have. He wants something more for his career, that's an evident sign of ambition. He won everything playing with all these stars [at Barcelona[ but he wants more and I'm really happy with that."

West Brom team news:

On loan from Arsenal, Serge Gnbary could make his first appearance for the Baggies having recovered from injury, while Sido Berahino is expected to lead the attack again despite ongoing speculation linking him with a move to Tottenham.

Chelsea team news:

Pedro Rodriguez, the man whose named dominated the gossip columns last week, could make his Chelsea debut this afternoon having trained with his new side since Thursday.

Full back Baba Ragman is also available for his first appearance, should Jose Mourinho chose to freshen up the defence that looked so disjointed in their 3-0 hammering to Manchester City last week.

Thibaut Courtois is expected to return in goal, after serving his suspension last week, but Oscar and Victor Moses remain out with injuries.
