More Chelsea pressure. They have had 71% of possession so far. Palace are still defending well, though, and are not letting the hosts get into their box.

Wilfried Zaha is picking out all the tricks today, dancing away from a couple of Chelsea defenders near the corner flag. It comes to nothing, but impressive none the less.

All the Palace players are working hard defensively, though, denying Chelsea space and keeping them at arm's length at the moment.

Here's a chance for Chelsea. Jason Puncheon involved at the other end this time, tangling with Diego Costa about 25 yards out. He pleads his innocence, but referee Craig Pawson gives the free-kick.

David Luiz steps up to take this one... and lifts it over the wall - but, again, it is straight at Wayne Hennessey.

It's been all Chelsea for the last few minutes but here's a reminder of the threat Palace pose too. Jason Puncheon is allowed to advance to the edge of the Chelsea area and lets fly with a low shot that is only a couple of yards wide of Thibaut Courtois's left-hand post.

The first save either keeper has made, really, and it's a good one. 

Eden Hazard and Cesc Fabregas combine again and Fabregas sends in a low cross that finds Diego Costa, who squirts in a shot as he falls over, bringing a superb block by Wayne Hennessey.

Pedro went off for treatment - and to get his breath back, I think. I had to do the same.

He was only back on for a matter of moments before being clattered again, this time by Andros Townsend. From the resulting free-kick, Palace managed to scramble the ball clear before it reached David Luiz on the edge of the six-yard box.

No more goals to tell you about but things are not exactly quiet at Stamford Bridge.

Chelsea want a penalty when Pedro is clattered - and winded - after getting his shot away in the box folllowing a corner... and could arguably have one anyway because the ball hit Andros Townsend's arm. I've seen them given... but not today by referee Craig Pawson.

Former England full-back on Final Score

You are meant to be at your weakest when you score but it was the opposite for Chelsea. They let Palace equalise and then were exposed again on the counter-attack - again. 

Chelsea take it quickly but referee Craig Pawson isn't ready and brings play back.

David Luiz is standing behind it but it is Marcos Alonso who goes for goal, lifting his shot over the wall but straight at Wayne Hennessey.

Palace had a very early corner but it was cleared at the near post. Chelsea are just settling down and now have a free-kick about 40 yards out after Luka Milivojevic fouled Cesc Fabregas...

Chelsea get us under way...

No Victor Moses for Chelsea - he is not in their squad against his former club. Pedro will play as right wing-back instead. 

Chelsea XI: Courtois, Azpilicueta, David Luiz, Cahill, Pedro, Kante, Matic, Alonso, Fabregas, Diego Costa, Hazard 

Palace XI: Hennessey, Ward, Tomkins, Sakho, Schlupp, Milivojevic, Cabaye, Puncheon, Zaha, Townsend, Benteke

It's in-form Chelsea versus in-form Crystal Palace so, what does Lawro think will happen at Stamford Bridge today?

"It is a big ask for the Eagles to extend that run of good form," says Lawro.

"Antonio Conte's side are getting so close to the finish line of the title race now, and they can win without playing well.

They saw off Stoke in their last match without ever looking that convincing and I think they will find a way to beat Palace too."
