The powerful frontman confirmed there had been interested in him - reportedly from Sporting Lisbon and Marseille - but said he will wait before deciding his next move.
"There is interest from clubs but I will decide at the end of the season," he said.
"Everton? I have heard about that in the papers. They are a very good team and a big club so it is flattering. Let's wait and see if it is real interest at the end of the season.
"Marseille would also be fantastic but let's wait and see."
