LONDON (AP)Chelsea maintained its unbeaten run under Graham Potter but had to settle for a point after a lackluster 0-0 draw at Brentford in the Premier League on Wednesday.

The Blues made the short trip across west London on the back of five straight victories in all competitions, winning each of the last four without conceding.

Once again they kept a clean sheet, but there was a distinct lack of cutting edge up front.

There was also another injury concern for England coach Gareth Southgate before the World Cup when midfielder Conor Gallagher limped off after 15 minutes.

Potter had made five changes from the team that beat Aston Villa 2-0, with Raheem Sterling and Pierre-Emerick Aubameyang dropping to the bench, but he had to make another switch when Gallagher trudged off.

Moments earlier, Ivan Toney – another World Cup hopeful for England – had a header from Mads Roerslev’s cross tipped over the crossbar by Kepa Arrizabalaga.

Chelsea had a let-off with 10 minutes of the first half remaining when Ruben Loftus-Cheek’s back-header from a free kick inadvertently let Toney in. The striker got to the ball before Kepa but was unable to direct his header on target.

The closest Chelsea came to scoring in a low-key half was an angled drive from Cesar Azpilicueta that goalkeeper David Raya tipped around the far post.

The Blues wanted a penalty for a handball against Rico Henry, and another when Kai Havertz tumbled under pressure from Ben Mee. They got neither.

Five minutes into the second half, Brentford’s Bryan Mbeumo had a free header in front of goal but the Cameroon forward sent it straight at Kepa.

From the corner, Mbeumo found Toney at the near post but his attempt at a glancing header flew wide.

Potter made a triple substitution on the hour but there was still no sign of Aubameyang, with teenager Carney Chukwuemeka sent on along with Sterling and Christian Pulisic.

But it was Brentford who came closest to snatching all three points when Henry’s shot crashed into the side-netting.

Aubameyang was finally sent on with 10 minutes remaining but his only half-chance was a low drive from outside the area which was easily gathered by Raya.

Spanish keeper Raya also beat away a swerving drive from Pulisic and saved with his feet from Chukwuemeka in stoppage time to preserve a deserved point for the hosts.
