Earlier today Turkish-football.com confirmed that Galatasaray are in talks with the Brazil international who is expected to leave United following their acquisition of Matteo Darmian from Torino.
United are keen to offload Rafael after the 25-year-old fell out of favour with manager Louis van Gaal and as his contract expires next summer.
Rafael is expected to miss United’s pre-season USA tour which begins on Monday.
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.
