Chelsea moved second in the Premier League and three points behind leaders Arsenal with a 2-0 win at lowly Burnley thanks to goals from Pedro Neto and Enzo Fernandez.
Neto's 37th-minute opener was the only moment of real quality in the first half as Jamie Gittens' excellent cross to the far post found Neto, who headed superbly back across goal and into the net.
Fernandez then made sure of Chelsea's third straight league win in the 88th minute with a powerful close-range finish after fine work by substitute Marc Guiu to set him up.
Team news
Burnley named an unchanged line-up from their 3-2 defeat at West Ham before the international break.
Chelsea made four changes from their home win over Wolves, with midfielder Moises Caicedo only fit enough for the bench after arriving late from international duty with Ecuador.
Andrey Santos replaced Caicedo, while captain Reece James, Jamie Gittens and Tosin Adarabioyo came in for the benched Malo Gusto and Alejandro Garnacho, and the absent Wesley Fofana.
Chelsea claimed victory without the influential Moises Caicedo, who was left on the bench, giving him crucial rest ahead of a crunch week for the Blues, who host Barcelona in the Champions League on Tuesday, followed by a home game against Premier League leaders Arsenal on Sunday, live on Sky Sports.
The Gunners, though, have the chance to restore their six-point gap ahead of next weekend's visit to Stamford Bridge when they host Tottenham in Sunday's north London derby, live on Sky Sports.

Chelsea did not have to work too hard for their win at Burnley, who managed just two harmless shots on target, with Zian Flemming volleying their best chance over in the 69th minute.
But the home side felt aggrieved in the first half over what they felt should have been a bizarre penalty after Trevoh Chalobah put his hand on Robert Sanchez's goal-kick, although referee Peter Bankes decided Sanchez had not taken it and was giving the ball to Chalobah to take.
What is not in doubt, however, is Burnley's poor form, with Scott Parker's side suffering a third straight defeat that leaves the 17th-placed side in danger of slipping into the relegation zone.
But at the other end of the table, Chelsea remain potential title challengers as they won a third straight away league game without conceding.
