Frei struggled to make an impact at Craven Cottage last season due to injury, while he was also loaned out to Championship side Cardiff City.
However, that has not prevented Galatasaray manager Fatih Terim from wanting to move forward with a potential transfer.
Terim told Lig TV: "We have been scouting Frei for over a year and we remain interested."
Frei has made four appearances for Turkey's national team.
