The Celtic summer signing has gone a little quiet of late.
Indeed, the former Bhoys defender has spoken of Ronny Deila's squad in glowing terms after Deadline Day, although it must be said many Celtic fans don't seem to share anywhere near the same level of optimism.
Neverthless, McKinlay, who played at Parkhead for five years, has backed 23-year-old Ciftci despite a slow start to life with the Scottish champions.
McKinlay is quoted as saying by the Scotsman: "I’m looking at the whole squad and I think it is fantastic. I’m more than confident that Nadir Ciftci will score goals for Celtic.
“I’ve always been an admirer of Leigh Griffiths too. He has a great scoring record and he has settled in at Celtic well. I’m sure he will go on to do well."
Ciftci was lauded for his immediate impact at Celtic, with the former Dundee United forward showing glimpses of quality and being unfortunate not to get off the mark for the Bhoys.
Slowly, though, that immediate impact waned. And the fact Ciftci is still yet to score for Celtic will soon become a burden for the forward - if it hasn't already.
Questions are being asked of the Bhoys' strike force as a whole and whether it is good enough for European competition, especially now that Celtic have been dealt a tough Europa League group.
But there are, of course, plenty who feel the 23-year-old will come good with time. And McKinlay is clearly one of them.
