A source close to Galatasaray told Turkish-football.com that head coach Jan Rierkerink has urged the board to strengthen the full-back position after a string of poor performances from his current defensive unit over the pre-season. The Istanbul giants conceded five goals against Manchester United last Saturday.
Gunners full-back Debuchy has been identified as being top of the Lions current shortlist for summer reinforcements in the full-back area.
Galatasaray have now entered personal talks with Debuchy after agreeing terms with his club.
Turkish football journalist Gökmen Özdemir with close links to the club also shared a tweet claiming Galatasaray have already reached a deal with the North London based outfit over the loan transfer.
Galatasaray could however, face competition from Bordeaux who loaned the 31-year-old over the second half of last season according to Sky Sports.
