Galatasaray are eager to purchase defender Kaan Ayhan, but Sassuolo are asking for €4m.
The 26-year-old only joined Sassuolo from Fortuna Dusseldorf in September 2020 at a cost of €2.5m.
He made just 20 appearances between Serie A and the Coppa Italia, starting only seven of them.
Born and raised in Germany, but playing his senior football for Turkey, this could be his first transfer to a Turkish club.
According to Milliyet, there are negotiations on-going with Galatasaray and the price-tag quoted to them is €4m.
