Everton have signed Brazilian winger Richarlison from fellow Premier League side Watford in a potential £50m deal.
The Toffees are believed to have paid an initial £35m for the 21-year-old - who has signed a five-year contract - with clauses that could make him the club's record signing.
Everton boss Marco Silva was managing Watford when they signed Richarlison for £11.5m from Fluminense in 2017.
"I want to have a lot of success with Everton,"Â said Richarlison.
"I think it is going to be important for me to be with Marco Silva again. I will learn more because I am still learning as a player and I aim to develop and grow here.
"I developed really well with him while he was with me at Watford. It was really good working with him and one day I believe he can help me to be selected for Brazil in the full national team.
"Everton have put their faith in me and I intend to honour this shirt and demonstrate on the pitch why I came here. I want my dreams to become a reality here at one of the biggest clubs in England."
Richarlison scored five goals in his first 12 Premier League matches but has not netted since November.
