Everton boss Roberto Martinez knows it will be difficult to keep hold of on-loan Chelsea striker Romelu Lukaku.
Lukaku is set to be a star in this summer's World Cup and that will make it even tougher for Everton to get him back to Merseyside on a permanent deal.
Martinez said: "He is going away with Belgium and his role with them is going to be incredible in the World Cup.
"And there are many factors in where he is going next season but we would like to keep Romelu for a longer period of course."
