Second-choice goalkeeper Filip Jorgensen went off injured against Pafos but has recovered sooner than expected following a scan and also makes a return to the squad.
Fellow goalkeepers Freddy Bernal and Max Merrick have also made the travelling squad but Robert Sanchez is expected to start between the sticks in Naples.
Chelsea will again be without Tosin Adarabioyo, who came off injured against Brentford, and there is also no Dario Essugo, who is out for three weeks after an unfortunate slip in training.
Longer-term absentees Levi Colwill and Romeo Lavia are also not involved, though Lavia is doing some level of training as he works his way back up to full fitness.
Romeo Lavia is back in training for Chelsea
Chelsea are expected to go strong against Napoli, as they will avoid two extra games in a play-off round if they manage to finish in the top eight in the Champions League. Ahead of the final round of games, they sit eighth.
Rosenior can choose between Liam Delap and Joao Pedro up front and may decide to rest Sunday’s match-winner Estevao in favour of using Pedro Neto on the right flank and bringing Alejandro Garnacho into the team on the left.

**Injured:** Lavia, Colwill, Tosin, Essugo
**Time and date:** 8pm GMT on Wednesday January 28, 2026
