The Istanbul giants are close to agreeing personal terms with the Brazil international who is expected to leave Old Trafford following the signing of Matteo Darmian from Torino.
Rafael is expected to miss Manchester United’s pre-season USA tour and part ways with the Red Devils over the summer.
Talksport’s Warren Haughton claims that Galatasaray could face competition from Napoli as well as Fiorentina who are interested in the 22-year-old right-back.
“Napoli, Galatasaray, Fiorentina all in for him and there were no specific denials form United from people I spoke to so it does look like he will be leaving,” told Talksport.
Galatasaray have made strengthening at right-back a priority over the summer transfer window after Tarık Çamdal failed to settle in last season.
Former Arsenal right-back Emmanuel Eboue has already parted ways with Galatasaray and Çamdal is also expected to leave.
Sabri Sarıoğlu will remain the only the first-team right-back unless another fullback is signed over the transfer window.
Rafael would become the Lions third Brazilian player should he join; Felipe Melo and Alex Telles being the other two.
