CELTIC may move for former £3.2million defender Hasan Ali Kaldirim in the summer.
The Hoops were linked with the Fenerbahce left-back during the January transfer window.
But they refused to pay the asking price for the versatile Turkish international who will be out of contract in June.
With Emilio Izaguirre possibly coming to the end of his seven-year career with the Six in a Row Champions, Brendan Rodgers will be on the look-out for cover for Kieran Tierney.
Kaldirim cost a huge fee when he joined Fenerbahce from Kayserispor in July 2012.
He kicked off his career at Bundesliga outfit Kaiserslautern in 2008 before moving to FSV Mainz a year later.
The attacking defender first came on the Hoops’ radar in October 2015 when he played in the Europa League tie at Parkhead when the Turks came back from two goals down to gain a 2-2 draw.
He also played in the 1-1 draw in Istanbul two months later.
The six-in-a-row champions will face a fight for the 27-year-old, though, with German double-act Stuttgart and Hertha Berlin eyeing a move for the player.
Kaldirim was born in Germany and as a result is able to play in Europe without a work permit – as an EU national.
He has made over 140 appearances since joining the Istanbul giants.
Former Sevco Rangers boss Dick Advocaat, who is retiring as the Fenerbahce coach at the end of the campaign, rated Kaldirim as one of his key players.
