Fluminense president Pedro Abad has confirmed Richarlison is set to join Watford.
Richarlison will move to Watford this week, his current club's president has announced, with a fee in the region of £11.2 million agreed.
Abad said: "Richarlison will not travel to face the next opponent. The exit is confirmed, he will play in Watford.
"It was all set on Friday, the last game would be on Sunday [yesterday]."
Richarlison already has 10 caps for Brazil Under-20s and has scored 15 goals for Fluminense in all competitions so far this season, which runs the length of 2017.
