Centre-backs Thiago Silva and Antonio Rudiger both scored as three second-half goals earned Chelsea a 3-0 triumph at Tottenham Hotspur to go level with Liverpool at the top of the table.
After an evenly contested first 45 minutes, N'Golo Kante came on at the break and an impressive second-half display followed.
Thiago Silva broke the deadlock on 49 minutes with a thumping header from Marcos Alonso's corner.
Kante, a replacement for Mason Mount, put the Blues 2-0 up with a shot that took a heavy deflection off Eric Dier.
Rudiger wrapped up a club-record sixth consecutive London derby away win in stoppage time, slotting in from a cutback by substitute Timo Werner.
Chelsea are joint-level with Liverpool on goal difference and goals scored, having both accumulated 13 points from five matches.
Spurs stay seventh with nine points.
