Antonio Rudiger scored twice as Chelsea secured a 2-2 draw at Leicester City.
In an end-to-end match, Leicester were denied a half-time lead through Jamie Vardy thanks to an excellent save by Willy Caballero, who started ahead of Kepa Arrizabalaga.
Chelsea made the breakthrough a minute after half-time as Rudiger headed in Mason Mount's corner.
Leicester hit back with two goals in 11 minutes as Harvey Barnes' deflected effort looped over Caballero and Ben Chilwell slotted in a low cross from Youri Tielemans.
But back came Frank Lampard's side and, from another Mount set-piece, Rudiger headed in again.
Barnes had a golden chance for a Leicester winner, but shot inches wide.
Leicester remain third on 49 points, with Chelsea a place below and eight points back.
