LONDON — Chelsea missed the chance to go top of the Premier League as Fabio Carvalho’s 93rd minute equaliser salvaged a 2-2 draw for Brentford in Saturday’s west London derby.

The world champions paid for Enzo Maresca’s experimental team selection as Kevin Schade fired Brentford into a first-half lead.

Substitute Cole Palmer led the Chelsea revival on his return from injury to equalise before Moises Caicedo’s thunderous strike looked to have snatched all three points for the Blues.

But Brentford’s persistent threat from long throw-ins got its reward at the death when Carvalho was left unmarked to tap in from close range.

Chelsea remain unbeaten this season but sit only fifth, one point behind the leading quartet of Arsenal, Tottenham, Bournemouth and Liverpool.

Maresca will wonder what might have been had he not seemingly had one eye on Wednesday’s Champions League trip to Bayern Munich.

Jorrel Hato struggled on his full Premier League debut, while Wesley Fofana only lasted 45 minutes on his first start of the season.

Facundo Buonanotte and Jamie Gittens were unimpressive in attacking areas as Chelsea were made to pay for wasting 45 minutes.

“I think we were much, much better (in the second half),” said Maresca. “I think we deserve to win the game but it’s a shame. We lost two points.”

Brentford saw Yoane Wissa join Bryan Mbeumo in leaving the club this week, stripping to Bees of a combined 39 Premier League goals last season.

The onus is on Schade to step into void left by the departed duo. The German delivered with his first of the season on 35 minutes.

Jordan Henderson’s through ball picked out Schade’s run and he cut inside Tosin Adarabioyo before firing into the bottom corner.
