Galatasaray are seeking a huge discount on Felipe Melo's original price to make his move from Juventus permanent.
Melo moved to Gala last season with the option to sign permanently for €11.5 million.
However, the Turks' last offer was €5 million for Melo, who is also interesting Manchester City AND MLS's Seattle Sounders.
Juve want to sell and could be prepared to accept Gala's offer with the need to raise cash quickly for their own market plans.
