Anderlecht insist that they will only sell midfield star Mbark Boussoufa for the right price.
The 25-year-old has been voted Belgium's Player of the Year for the last two seasons but he is now said to be looking to leave Brussels.
The Dutch-born Morocco international can play anywhere in midfield, and reports claim Aston Villa are ready to lodge an £8million bid for his services as they look for a replacement for James Milner - who is wanted by Manchester City.
With German side Hamburg also interested, Anderlecht have made it clear they will not sell the former Chelsea trainee on the cheap.
"Boussoufa can go if a team offers what we want," Anderlecht general manager Herman Van Holsbeeck told HLN.
"He was a key player and therefore he can only go if a club does what we ask. We will not make concessions."
