What happened: The Portuguese club is in advanced negotiations to acquire the 19-year-old for the upcoming season, according to Record. Prior to the expected departure, the English youth international agreed to a new long-term pact to remain at Stamford Bridge.

Why it matters: The maneuver secures his rights amid reported monitoring from Bayern Munich and Juventus. Shifting to Lisbon grants the academy graduate an immediate avenue for consistent first-team minutes.

What to watch: Final terms must be approved before the player travels for a medical assessment.
