The former Celtic man has been discussing the summer signing.
Indeed, while Viduka was a striker and Simunovic is a defender, McKinlay feels the fact the latter has signed from Dinamo Zagreb should not count as a disadvantage at all - as that's exactly where the former came from.
The Australian swapped Zagreb for Celtic in 1998 and the rest was history. And the club's most recent signing has been the subject of praise from former Bhoy McKinlay.
The 21-year-old only needs to be half as good as Viduka, he argues...
McKinlay is quoted as saying by the Scotsman: "Mark Viduka came over from Zagreb and he did not too badly at all. He was a fantastic player for Celtic and, if Jozo does half as good, then everyone will be happy."
Celtic fans generally appear to have been left underwhelmed by the Scottish champions' late business, including their Deadline Day deals.
The Bhoys faithful wanted a new striker but were left with midfielder Ryan Christie, who has been loaned back to Inverness Caledonian Thistle, and Simunovic.
But the signings of the latter, as well as Tyler Blackett on loan from Manchester United, were certainly necessary after the departure of centre-back Virgil van Dijk to Premier League side Southampton.
