Mancini may swoop in a bid to make him a Galatasaray player, if reports are right.
Mancini’s Gala side already boast the Turkish Super Lig’s most stingy defence, but they were spanked 6-1 by Real Madrid in Champions League action earlier this term.
Now Talksport suggest that the former City boss is keen to rescue Nastasic.
Having made 30 starts during Mancini’s last campaign at the club the Italian led to the title in 2011/12, the former Fiorentina man has yet to start three games consecutively this term.
