Welcome to our live comments from Brentford's Premier League clash with Chelsea in what should be a fascinating clash in London.

Wonderful overhead kick from Norgaard but Mendy again is equal to a Brentford effort and tips over the bar.

Four minutes of injury time to be played.

It is all Brentford. The ball falls to Jansson four yards out and he looks certain to score but Mendy denied him with a superb block with his head.

A diagonal ball is inadvertently flicked by Sarr towards Ghoddas at the far post but his effort is blocked by Mendy and then Forss squeezes the ball goalwards and Cholobah clears off the line.

Nice dink over the top from Loftus-Cheek but Raya came out of goal to dive at Werner's feet.

So close to a penalty! Cholobah pulled down Toney with the ball in the air, but the Bees striker was just offside so the referee could not point to the spot.

OFF THE POST! Mbeumo hits the post again! Forss managed to poke the ball beyond the Chelsea defence for him and Mendy was beaten but it came back off the post.

Jorgensen's long throw was flicked on by Pinnock and Toney's instinctive shot is parried away by Mendy.

Goddos comes on for Canos for the Bees.

Awful miss! Fine football from Chelsea with Mount playing into Kante and then on to Werner whose shot was blocked and then Lukaku waited for the ball to come down before blazing over the bar - he was then relieved to see he was offside anyway.

Jensen finds Toney in the penalty area but just cannot get the space to shoot and tries a backheel towards Mbeumo, which goes awry.

Onyeka is replaced by Forss for Brentford.

Mount comes on for Kovacic for Chelsea.

Fine ball from Kante towards Werner but Jorgensen got back to intercept the pass.

Toney is aghast not to get a free kick as he falls to the floor under pressure from Chalobah 25 yards from goal in a central area. A very interesting battle between two up-and-coming players.

A corner arrives at Canos on the left and he puts in a dangerous looking centre but Lukaku was there to head clear.

Nice tussle between Cholobah and Toney sees Brentford have a free kick 35 yards from goal they can swing into the danger area.

Chelsea in total control in this half so far.

Lukaku puts in a dangerous cross but Pinnock gets in a clearance in front of Werner.

Brentford get the second half underway...
