Galatasaray are seeking to outbid Turkish rivals Fenerbahce in the race for Daley Blind's signature, according to reports.
The versatile Manchester United defender has lost his place in Jose Mourinho's lineup despite starting the first three games of the season.
He has played just one minute of Premier League action since, with the Old Trafford boss preferring more regular left-backs Matteo Darmian and Ashley Young.
Blind was an important component in Louis van Gaal's United team, operating in central midfield, defence and as a full-back when required.
The club finished fourth in Turkey's Super Lig with Besiktas winning the title.
