Enzo Maresca says Brentford’s goal in Sunday’s chaotic west London derby is proof Chelsea cannot win the title - despite watching his side make it five Premier League wins in a row.The Blues extended their unbeaten run to 10 matches across competitions with a 2-1 triumph over Thomas Frank’s side at Stamford Bridge.Chelsea dominated much of the contest and led 2-0 thanks to goals from Marc Cucurella and Nicolas Jackson, only for Bryan Mbeumo to set up a nervy finish, with his 90th-minute strike leaving the hosts hanging on through seven minutes of stoppage time.Brentford were unable to find a leveller, though, and the win moves Chelsea to within two points of Premier League leaders Liverpool, who have one game in hand.
