Manchester United take on Swansea City on Saturday in their first game back from the international break.
Belgium international Marouane Fellaini is set to start following an injury blow to Scott McTominay.
The Scottish midfielder returned from international duty with a minor injury problem and will not be risked this weekend.
Turkish-Football can confirm that Galatasaray, Besiktas and Fenerbahce will be scouting Fellaini as they have done throughout the season.
The Lions are currently favorites among the three interested Super Lig clubs and have made Fellaini a priority.

Besiktas have cooled interest of late but continue to monitor the situation.
Fenerbahce meanwhile are keen on a four-year deal but any formal offer could have to wait until the presidential elections in May.
Fellaini will be a free agent at the end of the season unless he signs an extension deal.
