The Blues announced on Tuesday evening that the 22-year-old had put pen-to-paper on a deal that will keep him at Goodison Park until 2024.
Richarlison told evertontv: “I intend to be here a long time.
“This was the club which gave me the opportunity to show my football.
“It was here I managed to get a place in the Brazil national team and it was here I have scored lots of goals in the Premier League.
“The club trusts me and I trust them. The supporters have a lot of affection for me and I try to give back all this affection as much as possible on the pitch.
“I go out and put my life on the line for them. I try to sweat blood and tears for this club. I intend to continue honouring the shirt and making the fans happy.
“And I hope they continue singing my name.”
