Ciftci, 23, may be familiar to some having previously played for Portsmouth, but left Fratton Park in 2011, and after spells with Kayserispor and NAC Breda, the Turkish forward is now in Scotland with Dundee United.
After 17 goals for Jackie McNamara's men last season, Ciftci has now found the net 14 times this term, continuing to build his reputation in Scottish football - and triggering transfer speculation as a result.
Recently, the Daily Mail reported that Celtic wanted to sign Ciftci as a replacement for John Guidetti this summer, with the Swedish striker set to leave Celtic Park at the end of his loan deal.
However, the Bhoys could now face competition from up to five English clubs as Ciftci's exploits in Scotland are no longer a secret.
The Sun report that relegated Premier League club Queens Park Rangers are interested in Ciftci, as well as Championship clubs Charlton Athletic, Huddersfield Town, Rotherham United and Wolverhampton Wanderers.
It's tough to gauge how this would impact Celtic; on the one hand, getting a move to England could be huge for Ciftci's career, but on the other, Celtic will be back in the Champions League qualifiers this summer - and the opportunity to play in Europe's elite club competition could swing it in the Bhoys' favour.
Manager Ronny Deila may now need to move quickly this summer if he is to make sure Ciftci is a Celtic player, with interest seemingly building from clubs south of the border.
