Richarlison was heavily linked with a move to top European clubs like Paris Saint-Germain and Barcelona.
The Olympic medalist was also speculated to have a reunion with his former boss Carlo Ancelotti at Real Madrid after the Italian tactician left Everton.
Feeling happy at Goodison Park, the former Watford goal-getter has claimed he's unsure of his future.
"I'm always very careful when I talk about it. I have great affection for the people of Everton and for the club, who received me so well from the first day I arrived.
"I don't know what the future holds. If one day I have to go, it must be good for me, but also for the club.
"But if I stay, I will continue giving my life for this shirt and for the fans, who have always supported me and were with me at all times.
"I have enormous gratitude and feel at home when I am at Finch Farm training ground or Goodison Park stadium."
Richarlison guided Brazil to a Copa America final where they were defeated 1-0 by Argentina before leading the Olympic men's team to a trophy success in Tokyo.
Scoring 7 goals with three assists in the Premier League last season for Everton, the 24-year-old who missed the side's 2-0 victory over Norwich at the weekend due to a knee injury has just one goal to his name thus far.
