Chelsea and Arsenal played out an intense 1-1 draw at Stamford Bridge in the Premier League on Sunday afternoon.
The Blues started the game well, but their plans were thrown into disarray when Moises Caicedo was sent off for a reckless challenge on Mikel Merino after a lengthy VAR check.
Enzo Maresca's side showed their resilience though, and Trevoh Chalobah put them ahead as he nodded home from Reece James' corner early in the second period.
However, Merino levelled for the Gunners soon after following good work from Bukayo Saka - and the two sides could not be separated from then on.
