The agent of David Henen expects him to remain with Everton next season.
The Belgian has spent this season on loan at Goodison Park, playing in the Blues' U21 squad, but is now due to return to parent club Olympiacos.
Agent Christophe Henrotay told the Liverpool Echo: "I have to quickly meet (Roberto) Martinez. But all the signals go in the direction of exercising the option (of a permanent deal)."
Henrotay added: "He really changed beyond all recognition. The reports of Martinez and the U21 coach are very favourable. Both praise his mentality, his involvement and his integration."
