The former Liverpool FC, FC Barcelona and Bayern Munich star returned to his hometown club in 2024 after a spell in England with Aston Villa.
However, growing criticism from supporters has reportedly left him eager to seek opportunities elsewhere.
According to Globo, Coutinho informed club president Pedrinho directly of his desire to end his current deal.
The request is said to have surprised Vasco’s hierarchy, who have attempted to persuade the attacking midfielder to reconsider.
Despite ongoing renewal talks, the recent accumulation of criticism, including boos from fans and scrutiny from local media, has reportedly made his situation at the club untenable, with Coutinho believing his decision is now irreversible.
