At least until tomorrow's game between West Ham and Liverpool, Manchester City in second place and three points away from Chelsea.
This is after the leader lost points tonight (Saturday) in the home game against Burnley.
Again without Timo Werner and Romulo Lukaku Thomas Tuchel's team took the lead in the 33rd minute when Chris James cooked for Kay Habertz his second goal of the season in the league, but the sequel was less accurate.
Nick Pop's series of misses and good ability at Burnley's goal prevented the second and prepared the ground for the equalizer that came in the 79th minute.
Jay Rodriguez cooked for Matty Vidra, who came in a few minutes earlier and set up a very surprising 1-1 draw at Stamford Bridge.

And yet, this was not the most surprising result of the cycle.
Norwich, for their zero wins this season in the league, hosted Brentford and came away with a 1-2 win and first three points.
Matthias Norman's first Premier League goal and Timo Poke's penalty gave the Canaries a 0-2 lead that stopped in front of a shrinking goal from Rico Henry half an hour to go.
Crystal Palace continued their good period with 0: 2 over Wolves from goals by Wilfried Zaha and Conor Gallagher.
