Reports seems to have believed that the Toffees signed the attacker with an initial fee of £35m having put pen to paper to sign a five year deal with the club with a release clause which set him on the order of being the club’s record signing.
Everton manager, Marco Silva was still in charge at Watford when the 21-year-old winger move to the Vicarage Road signing from Fluminense for £11.5m last summer.
“I want to have a lot of success with Everton,” 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.”
After succeeding in replacing Sam Allardyce as Everton boss, Silva has been desperate to bring in the Brazilian star.
“Richarlison is a good player who will make our team and our squad more competitive,” said Silva. “The competition between our players is really important to me.
“The player himself is fast, strong, very good technically and he can play in three positions across the front line. He can also score goals.”
Richarlison scored five goals in his first 12 Premier League matches with Watford but couldn’t find the back of the net since then.
