Nigel Pearson, who's been linked with the Aston Villa, Middlesbrough and Celtic manager positions, is a long-term target for the Bhoys, according to a 2010 report by the Daily Mail.
The Daily Express claimed on Wednesday that Pearson's name has been discussed at length by the Celtic hierarchy, as majority shareholder Dermot Desmond looks to filter down a shortlist of names to replace the departing Ronny Deila.
And Desmond, along with chief executive Peter Lawwell, were both at Parkhead six years ago when Pearson was reportedly being considered as Tony Mowbray's permanent replacement.
However, Pearson, who was in his first spell at Leicester City at the time, was eventually overlooked in favour of caretaker boss Neil Lennon, remaining at the King Power Stadium for the Foxes' unsuccessful Championship play-off campaign.
The 52-year-old, a free agent since leaving Leicester last summer, is currently odds-on to take the reins at Villa Park and was recently linked with the Middlesbrough post, which, as reported by the Daily Mail, could be vacated by Aitor Karanka whether his side are promoted or not.
David Moyes, Brendan Rodgers and Lennon are among the bookies' favourites to replace Deila at Parkhead.
