Watford have signed attacker Richarlison from Fluminense, with the Brazil under-20 international signing a five-year contract.
Richarlison, 20, had been linked with Premier League champions Chelsea, Europa League runners-up Ajax and Brazilian side Palmeiras.
But last week Fluminense said they had agreed a deal with Watford, and reports in Brazil said the Hornets would pay a transfer fee of between £11 million and £13m.
Former America Mineiro man Richarlison scored five goals and provided three assists in 14 Serie A games last season.
Overall, he played 67 games for the club and scored 19 times, adding two more goals in eight games for Brazil U20s.
