Christian Pulisic hit a perfect hat-trick to guide Chelsea to their fourth successive Premier League win with a 4-2 victory at Burnley.
Pulisic, who had not scored for his new side before the match, became the first American to net a Premier League treble since Clint Dempsey in 2012.
The 21-year-old opened the scoring on 21 minutes with a surging run and left-footed shot.
He added his second on the stroke of half-time with a low finish with his right, before completing his treble with a header from Mason Mount’s cross after the break.
Willian added his name to the scoresheet on 58 minutes with a fierce strike from Tammy Abraham’s pass.
Burnley threatened a comeback with two late goals, both of which were assisted by substitute Robbie Brady.
First, Jay Rodriguez scored a stunning long-range effort, before Dwight McNeil’s deflected shot further reduced the deficit.
Chelsea remain fourth, trailing Leicester City in third on goal difference.
Burnley drop to 11th place on 12 points.
