Galatasaray are chasing Chelsea defender Gary Cahill.
The ex-England centre-back, 33, left Chelsea this summer and the Turkish giants are among suitors who want him on a free.
Blues legend Didier Drogba, 41, spent a year in Istanbul and his old club hope he can talk his former team-mate into finishing his career at a Champions League club.
They will be able to offer bigger wages than the Championship clubs who are chasing Cahill.
The Sun says the English defender is a target for Leicester - who are braced to lose Harry Maguire this summer.
Both Manchester clubs are in for the Foxes centre-half - with Old Trafford chiefs leading the race but are yet to match the £85million price tag.
