Benfica are the latest team to be linked with a move for Manchester United right back Rafael.
According to the Portuguese paper A Bola, United are set to offer Rafael plus money in-exchange for Nicolas Gaitan.
United are expected to sell Rafael this summer following the imminent arrival of Darmian from Torino.
Galatasaray are also considering an offer for United fullback Rafael according to Turkish sports newspaper AMK.
The report states that Hamza Hamzaoğlu wants to sign a right-back over the summer and that Rafael has been added to the shortlist.
The Lions have made strengthening at right-back a priority over the summer transfer window after Tarık Çamdal failed to settle in last season.
Sabri Sarıoğlu will remain the only the first-team right-back unless another fullback is signed.
Rafael provided one assists and scored one goals in 17 appearances for Manchester United last season.
