Chelsea boss Antonio Conte says striker Alvaro Morata improved "a lot" in the last ten days and is a contender for a regular place for today's game.
The Spaniard struggled to keep up with the pace of the game last Sunday against Arsenal.
But he is expected to start against Burnley with Michy Batshuayi on the bench.
"Alvaro is working well and has improved a lot over the last 10 days in terms of his physical condition," Conte told reporters.
"He is starting to understand what I want from him during the game but for sure he needs time to adapt.
"For me, the striker has a really important role and it's important for them to understand what positions I want them to take up. This role is more difficult to adapt to than others.
"We have been working very well and I must be pleased with the commitment of my players. It's a pleasure for me to see this every single day."
