The Brazil international is currently on loan at Galatasaray, but the Istanbul giants are having doubts about whether to exercise their option to buy the player permanently
Melo joined the Istanbul giants on a one-year loan deal at the start of the season, and Galatasaray have the option to make the midfielder's stay at the club permanent for a set fee of €13 million.
Galatasaray head coach Fatih Terim is believed to be satisfied with Melo's performances this term, and has asked his board to keep the former Fiorentina star at the club.
However, Galatasaray are reluctant to shell out €13m for the holding midfielder, and could therefore decline to exercise their option to buy.
Melo recently stated that he is keen to stay at his current club beyond his current loan spell.
