Hoeness has slapped a €100million price tag on the former Marseille star.
“If I hear that there was an offer for 125m euros (£109m) for Kaka, then Ribery has a market value of at least 100m (£87m),” Hoeness told the Bild newspaper.
“But I don’t want to talk about a fee we would consider because we want to keep hold of Franck.”
