Chelsea were comprehensively swept aside by Brighton in their 2-1 defeat on Saturday afternoon.
It was the third game of Frank Lampard's tenure since taking charge on an interim basis and the third match that the Blues have lost.
They took the lead early on thanks to Conor Gallagher's deflected strike, which looped over Roberto Sanchez in the Brighton goal.
But the Seagulls fired back through Danny Welbeck before half-time and then later found a winner through Julio Enciso's long-range striker.
