Ancelotti has pushed Everton to move for the striker and a bid is now being prepared.
For their part, ASSE are reluctant to lose Bouanga and are even drawing up new contract terms for his consideration.
Just last week, Bouanga's younger brother Didi said: "Obviously, he dreams of playing the World Cup with our country, Gabon.
"But he also dreams of playing in the Champions League. I told him it's time, he has to go to a club that plays the Champions League.
"Maybe next year, we'll see. The important thing is that he continues to progress like this!"
