Callum Hudson-Odoi refused to comment on his future after starring for Chelsea in their FA Cup victory over Sheffield Wednesday.
Hudson-Odoi handed in a transfer request on Saturday having been the subject of several bids from German giants Bayern Munich.
But the 18-year-old was named in Maurizio Sarri's starting XI for Sunday's fourth round tie, getting on the scoresheet after a fine moment of individual skill.
Hudson-Odoi was quizzed on his future after the final whistle, asked if this might have been his last game for Chelsea.
He told BBC Sport in response: "I don't know. I can't say. I just keep working hard and you never know what happens.”
Hudson-Odoi has been the subject of four bids from Bayern this month, the last of which was £35million.
Bayern are confident the 18-year-old has already made up his mind and wants to join them.
The German champions have until 5pm GMT on Thursday, January 31 to get a deal across the line.
