Brentford players and fans bay for a penalty as Ivan Toney goes down in the box under a tug from Trevoh Chalobah, but the flag goes up and saves the Chelsea defender.

Brentford have hit the post again!

And it is Bryan Mbeumo once more, finding room to get a shot off in the area, Edouard Mendy is beaten on this occasion but the ball rattles the foot of the post.

Brentford finally call Edouard Mendy into action, it's only taken 73 minutes.

Striker Ivan Toney stretches round a defender to swing a snapshot at goal, but the Chelsea goalkeeper is equal to it by parrying away to safety.

The mark of an excellent keeper, remaining awake despite not having much work to do.

'os' on, 'os' off.

Saman Ghoddos replaced Sergi Canos.

18 left.

Steve In Milan: This is a second string Chelsea but Brentford haven't played a team like this yet.

What a miss, absolute sitter. The flag may be up Romelu Lukaku has somehow scooped his effort over from six yards out.

A really streaky player, scored four goals early on for Chelsea but this will be his six game for the club without a goal.

Khan Karn: Surely deliberate foul on last man Toney by Chalobah, arm on him as well as leg trip! Is Anthony Taylor afraid to give the decision against Chelsea again? That should have been freekick to Brentford and red card for Chelsea.

Why didn't he shoooooot?

Brentford finally prise the Chelsea backline open, working it well and Ivan Toney takes the ball in his path in the box.

He can bend one into the far corner, there's space, but decides to chop back and his backheeled pass is cut out.

What a waste.

Nick Bruzon: And I thought we had issues in the Championship with some of the referees but Mr. Taylor is next level atrocious. A great game being ruined by myopia.

Frank Onyeka soldiered on after that early knock but now he is coming off.

Finn Marcus Forss comes on.

Here's Mason Mount entering the action for 26 minutes.

The England international replaces Mateo Kovacic.

Mount offers something a little different in the final third.

That is why he is the captain.

Goalkeeper Edouard Mendy is struggling to tie his boots, wouldn't you with gloves on?, so skipper Cesar Azpilicueta comes across to lend a helping hand.

They quickly resolve the issue.

Not much goalmouth action to speak of so far in this second period.

Chelsea have the lead but Brentford are still in this and aiming to pose a threat in the final third.

Easier said than done against this Thomas Tuchel team.

I watched Liverpool at lunchtime, then covered Manchester United in the afternoon, now doing Chelsea in the evening.

You have to say, Ole Gunnar Solskjaer's side are miles behind those two.

Liverpool firing on all cylinders with the best player in the world, Chelsea yet to concede from open play eight games into the season.

Chelsea and other Premier League clubs are going to have to take note:

Any ball pumped into the box and David Raya is going to be out for it.

This one he claims right on the edge of the box over the head over Romelu Lukaku.

I love that sort of goalkeeping.

Oh dear.

Can we have our ball back? Mateo Kovacic goes for glory but sends his effort out of the stadium.

Richard H: Has Marcus Alonso been imparting all his sage wisdom on the art of making a career as a defender whilst doing very little defending to Chilwell? Struggling to tell the two apart these days
