Now Diego Costa has come alive! 

The striker shoots hard and low from the right side of the area, Alex McCarthy keeps it out but pushes the ball straight to Cesc Fabregas in the middle of the area. He'll surely score? No! McCarthy reacts quickly to produce a superb double-save.

Chelsea striker Diego Costa will be hoping to have more of an involvement inside the penalty area. 

His touch map below shows he is struggling to make an impact early on.

"Chelsea have had so much of the ball but have tried to walk it in. It's against a very organised Crystal Palace defence. Maybe they should be trying their hand from distance?"

Wondering why I haven't mentioned Diego Costa much? He has barely been involved, having managed just six touches of the ball so far but he is inches away from connecting with a Cesar Azpilicueta cross.

A few groans of frustration from the home crowd as Chelsea squander another promising build-up. 

Pedro, who has swapped sides with Eden Hazard and is now operating on the left, passes to Cesc Fabregas on the edge of the area but the midfielder is loath to shoot, instead teeing up Gary Cahill to launch a shot well, well over from 25 yards. 

Great chance for Crystal Palace! 

Wilfried Zaha skips the challenge of several lunging feet to get inside the area and places the ball into the path of Yohan Cabaye on the edge of the area. 

He's been left unmarked and only has Thibaut Courtois to beat, but the shot lacks conviction and is straight into the Chelsea stopper's hands. 

Let off for the hosts.

Both sides very much using their flanks, with Chelsea mostly using their right and Crystal Palace attacking down the left. The hosts have had almost 70% of possession.

Chelsea have been doing most of the attacking but Crystal Palace's pace is capable of catching them on the counter. A good ball from midfield cuts out Branislav Ivanovic and releases Bakary Sako, whose low drive is pushed behind by Thibaut Courtois. 

From the corner, Palace's fourth of the game, Yohan Cabaye shoots way over.

Diego Costa is not happy. Replays show the striker getting a shove from Damien Delaney and it almost lights the fuse. Costa keeps it calm though. For now.

The ball comes in from the corner and Kurt Zouma tumbles to the floor under the challenge of Connor Wickham. Nothing given, but a tad clumsy from Wickham.

This if the first time I've properly seen Pedro in a Chelsea shirt and I've been impressed with what I've seen so far. Lively and full of running, he is certainly taking a bit of the pressure off of Eden Hazard and he goes close as he curls a shot just wide from the edge of the area.

Corner now to Chelsea...

Next, Willian fires over after good work by Pedro. 

Chelsea are dominating possession, but Crystal Palace are largely limiting the hosts to half chances so far.

First shot on target and it comes from Chelsea but it is nothing more than a bit of shot-saving practice for Alex McCarthy as he gets down to gather a Cesc Fabregas strike that lacked bite.

Crystal Palace are focusing their early attacks down Chelsea's right, targeting Branislav Ivanovic.

The full-back has not had the best of starts to the season and has been off the pace a little in these early stages. 

The pressure is certainly on, especially with full-back Baba Rahman watching on from the bench today...

Branislav Ivanovic is then back defending as Wilfried Zaha attempts a shot from the left, which Ivanovic blocks and the ball loops onto the roof of the net.

Palace have their third corner inside just seven minutes but it comes to nothing.

Warm applause from the Chelsea fans as Pedro - on his home debut - races across the pitch with the ball, determined to make an impression. 

He has Chelsea's first shot on goal, but his effort strikes a defender and the ball rebounds to Branislav Ivanovic, who hacks way over the bar.

Nice touch from Jose Mourinho just before kick off.

Yannick Bolasie is back in the Crystal Palace squad after he was away on compassionate leave following the death of his father.

Mourinho sought out Bolasie before kick off and gave him a hug.

Chelsea beat Crystal Palace 1-0 at Stamford Bridge back in May to secure the Premier League title.

Today they face them with their defence yet to really get up and running.

Will the Blues give Jose Mourinho something to cheer about with victory today? 

Crystal Palace get things under way...

"Even with John Terry getting sent off, I thought Chelsea got back to business last week with their win at West Brom.

"Meanwhile, Crystal Palace continued their strong start by beating Aston Villa and the pressure is off them a bit here.

"Even if they lose at Stamford Bridge, the Eagles will have played two of last season's top four in their first four games, and still have six points. Everything is very rosy for them at the moment."
