Christian Eriksen scored a fairytale goal as Brentford embarrassed Chelsea 4-1 in their own back yard.
13 minutes of second-half madness began with Antonio Rudiger giving the Blues the lead with a 35-yard screamer. But two well-taken strikes from Vitaly Janelt sandwiched Eriksen's latest milestone in his incredible comeback after suffering cardiac arrest just nine months ago.
That allowed super sub Yoane Wissa to wrap things up with a smart finish to put the icing on the cake, only two minutes after being brought on. Saturday's historic result moves Thomas Frank's team up to 14th in the Premier League table, 11 points clear of the relegation zone.
