Chelsea directors Marina Granvoskaia and Petr Cech's reactions to Yoane Wissa's goal for Brentford summed up a bad day for the Blues on and off the pitch.
The pair initially witnessed jubilant scenes as Antonio Rudiger had scored a wonder strike just after the half-time whistle, but that goal alone sparked a remarkable response from Brentford, who turned into prime Barcelona with their clinical nature shortly after.
A double from Vitaly Janelt coupled with a special goal for Christian Eriksen and a late strike for the DR Congo international meant that the Bees enacted sweet revenge on their London neighbours for the fortuitous 1-0 win that Thomas Tuchel's side picked up in the reverse fixture earlier this season.
