Few inside Stamford Bridge could comprehend the madness ensuing in Saturday's second half as Brentford put four past Thomas Tuchel's Chelsea to accomplish one of the shocks of this season.
The Blues' seven-game winning run in all competitions was emphatically ended by Thomas Frank's inspired Bees who responded to a wonder strike by Antonio Rudiger, netting three goals in a bizarre 10-minute period that silenced the home crowd and condemned Chelsea to their first league loss since mid-January.
Another telling statistic that came out of this shock defeat further proved how maddening this result was and how it compared to a weirdly similar outcome 12 months ago.
