Despite agreeing to a new four-year contract last summer, the Belgian's representative has refused to reveal whether his client will see out the deal at Villa Park.
A number of clubs ended their interest in the 23-year-old due to the extension, but Villa may be forced into a battle to keep hold of the forward if he performs well at the World Cup in Brazil.
"He wants to get ready for the World Cup," Eric Kismet is quoted as saying by The Mirror. "For the future, there is time. Currently it is too early to talk about it."
Benteke joined the club from Genk in August 2012.
