Chelsea have received a major boost ahead of their Premier League meeting with Sunderland, with Emi Martinez returning to first-team training after recovering from a fractured jaw.

According to a report by London Evening Standard on Friday, November 6, 2026, the Argentine goalkeeper has resumed training at Cobham while wearing protective facial equipment, raising hopes that he could be available for Sunday's encounter at the Stadium of Light.

Martinez sustained the injury during Chelsea's victory over Everton last month. His recovery has progressed ahead of schedule, although head coach Xabi Alonso must decide whether to restore him immediately or continue with Mike Penders, who impressed during his absence and kept a clean sheet against Manchester United.

Moises Caicedo is another concern for Chelsea after experiencing discomfort following the 2-0 victory over Manchester United.

The midfielder was not spotted during the portion of Wednesday's training session open to journalists, leaving his availability in doubt ahead of the weekend fixture.

Meanwhile, Aaron Anselmino has returned to training after recovering from an injury and has also received an international call-up from Argentina.

Romeo Lavia could retain his place in midfield after delivering an impressive performance against Manchester United, while Estevao is pushing to keep his starting position following his encouraging display.

Chelsea, however, remain without several injured players. Joao Pedro, Maxence Lacroix and Jorrel Hato are still sidelined, while captain Reece James continues his recovery from knee surgery and is not expected back until January.

Jamie Gittens is also unavailable after suffering an ankle injury while representing England Under-21s last month.

Alonso could therefore make limited changes to the side that defeated Manchester United, although the fitness of Martinez and Caicedo will influence his final selection.

Chelsea's predicted starting XI (3-4-2-1): Penders; Acheampong, Fofana, Colwill; Neto, Caicedo, Lavia, Chavarria; Estevao, Palmer; Rogers.

Injured: Joao Pedro, Reece James, Maxence Lacroix, Jamie Gittens and Jorrel Hato.

Doubts: Emi Martinez and Moises Caicedo.

Martinez's return provides Chelsea with an important selection boost, but Alonso must carefully assess his fitness before deciding whether to make changes to the team that secured victory over Manchester United.
