Bryan Mbeumo and Ethan Pinnock were on target as Brentford won 2-0 at Chelsea to triumph at Stamford Bridge for a historic third season in a row and end the Blues’ recent revival.
Mauricio Pochettino’s home side had dominated the first 45 and carved out a series of good openings, but could not find the breakthrough with Noni Madueke going closest with a shot that came back off the frame of the goal.
Brentford defended for their lives at times but offered more of a threat following the interval with Vitaly Janelt firing straight at Robert Sanchez from 15 yards out.
It was a let-off for The Blues, but they did not heed the warning and The Bees stole in front on 58 minutes when Pinnock nodded in Mbeumo’s right-wing cross.
Chelsea huffed and puffed but rarely looked like rescuing a draw and Mbeumo rolled in a second deep into stoppage time to clinch the points.
The result means Brentford leapfrog above Chelsea into 10th place on 13 points ahead of the rest of the weekend’s action. The Blues are one point further back in 11th.
Chelsea will now switch focus to the EFL Cup tie at home to Blackburn on Wednesday before visiting Tottenham next Monday. Brentford host West Ham next Saturday.
