Watford are set to sign Brazil U20 star Richarlison from Fluminense, subject to a medical.
Sky Sports News understands the Hornets have agreed a fee of £13m with the Brazilian club and the striker has agreed terms on a five-year contract.
Richarlison, who is just 20 years old, is currently in England and will undergo a medical with Watford on Tuesday. His move is also subject to a work permit being secured.
The forward, who can also play off the left or right, scored five goals in 14 appearances for Fluminense last season.
Richarlison also has 10 caps and three goals for Brazil's U20 side, having made his debut in 2016.
The Nova Venecia-born player began his youth career at Real Noroeste before switching to America Mineiro's academy, from which he graduated into senior football.
