Watford have confirmed the signing of Brazil Under-20 international Richarlison after he was granted a work permit.
The 20-year-old forward has joined on a five-year contract from Fluminense for about £11m.
Richarlison was signed by Brazilian top division side Fluminense from second-tier side America Mineiro 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.
He made 67 appearances for Fluminense and scored 19 goals, while he has two goals in eight Brazil U20 outings.
