Good morning, everybody, and welcome to our LIVE coverage of Chelsea v West Brom.

FULL-TIME. Nine in a row for Chelsea, who inflict West Brom's first defeat in five games, and return to the top of the Barclays Premier League Table. It wasn't always pretty, but a piece of excellence from Diego Costa proved the difference. Thanks for your company this afternoon.

Four minutes to be added on here.

After all that hullabaloo about West Brom wasting time, Matic gets a booking for that particular crime.

Fabregas thinks Dawson has got a touch to nudge the ball out for a corner, but once again referee Dean does not agree.

Dawson tries to take advantage of some confusion in the box, but finds himself with perhaps too much time and bundles the ball over the bar.

Robson-Kanu on for Brunt.

Chris Brunt's corner slices through the gathering of bodies in the box, and Chelsea break again.

And Chelsea make a change as well.

And the second.

Two substitutions for West Brom.

GOAL! And Diego Costa takes advantage of the only mistake West Brom have made at the back all afternoon, racing down the right and then lashing it into the top corner.

A corner to Chelsea, which Fabregas takes, but Foster claims that with confidence.

Fabregas replaces Moses, who, let us not forget, was pulled up for a foul throw earlier.
