Not much flow to this game. It has been very scrappy and the number of fouls being conceded means players have not been able to find any rhythm.

David Franklin: Never a penalty - Oscar left his left foot out to seek contact. Would've been a yellow if the ref had been 100% sure
Sho Rahman: Never a penalty. The arm on Oscar was minimal.

I feel it was a penalty because there was enough contact from Winston Reid. Anthony Taylor seems happy enough to book players, particularly Diego Costa when he went running after him asking for a penalty.
Chelsea 0-0 West Ham
Another booking, this time West Ham defender James Collins for tripping Diego Costa from behind.
Costa starting to warm up, he will ruffle a few feathers.
Chelsea 0-0 West Ham
Meanwhile, Chelsea striker Diego Costa ran 30 yards to scream at referee Anthony Taylor for not awarding the penalty.
Under new legislations, it means Costa goes into the book. He had best be careful this season.
Chelsea 0-0 West Ham
West Ham midfielder Mark Noble gives the ball away to Oscar on the edge of his own area and the Brazilian goes down in the box under the challenge of West Ham defender Winston Reid.
Nah, soft lad. Get up. Correct decision from Anthony Taylor.
Chelsea 0-0 West Ham
Chelsea boss Antonio Conte, a brilliant midfielder back in the day for Juventus, playing alongside the likes of Alessandro Del Piero, brilliantly controls the ball in his technical area as the ball runs out of play.
The home crowd enjoyed that one.
Form is temporary, class is permanent.

Winston Reid is a big strong lad with plenty of pace. West Ham are so good from free-kicks at the moment. If you give away a set-piece he's the type of player that could punish you.
Chelsea 0-0 West Ham
Eden Hazard, PFA Player of the Year two seasons ago, did not have the best time of it last season. Will we see more of him this campaign?
The Belgian finds space on the edge of the box, but after taking a touch, lashes his strike over the crossbar.
New Belgium boss Roberto Martinez, who is watching on from the stands, will not be impressed by that.

Branislav Ivanovic coming in on to his left foot but the Oscar back heel that put him in was a great bit of vision.
Chelsea 0-0 West Ham
West Ham sweeping the ball around nicely, but it's Chelsea who draw the first save.
It's right-back Branislav Ivanovic who gets forward, making a neat turn in the box to escape the attention of Cheikhou Kouyate, before striking a low shot at the front post of Adrian, but the Spanish goalkeeper gets down well to push the ball away.

James Collins was shown a clear set of heels by Diego Costa, who looks really sharp and is picking on Collins with his pace.
Chelsea 0-0 West Ham
Visitors West Ham have started this game the better, getting their foot on the ball and have had 60% of possession so far.
Chelsea have not woken up yet.
Chelsea 0-0 West Ham
It's a poor free-kick by Enner Valencia from a promising position, scuffed into the area and Chelsea themselves are given a free-kick for a foul on goalkeeper Thibaut Courtois.
A let-off for the home side.
Chelsea 0-0 West Ham
These two sides are really getting stuck in already. This time Chelsea defender Gary Cahill hauls Andy Carroll over and Enner Valencia stands over a set-piece about 30 yards out
Chelsea 0-0 West Ham
Barely three minutes in and N'Golo Kante has received a very early yellow card.
Having tackled Andy Carroll earlier, he tries the same two minutes later but mis-times it and fouls the England striker.
Referee Anthony Taylor feels it warrants a booking and the Frenchman is now treading a fine line for the remaining 87 minutes.
Chelsea 0-0 West Ham
Chelsea striker Diego Costa earns a free-kick on the left, which Willian pumps into the box, but Andy Carroll, doing his defensive duties for West Ham, heads the ball away.
Chelsea 0-0 West Ham
And so it begins.
N'Golo Kante makes his first interception in a Chelsea shirt, nicking the ball away from West Ham striker Andy Carroll.
The first of many for the Frenchman.

Jonathan Pearce
Match of the Day commentator
"Many people are tipping Chelsea to challenge for the title under new boss Antonio Conte. He's a charming passionate football man with steely, ambitious eyes.
"N'Golo Kante will add a pacy engine to a flagging midfield. But it's a big step up for £33m striker Michy Batshuayi. The Conte evolution may take time.
"West Ham surprised everyone by winning at Arsenal on the opening day last year. They could spring another one here.
"New boys Sofiane Feghouli and Ashley Fletcher have looked sharp in pre-season. Andre Ayew's a good signing. A top-five challenge should lie ahead.
"This is a thrilling score draw for me."
