Celtic also contacted Eddie Howe in their ongoing hunt for a substitute for Neil Lennon. Howe is said to be considering a variety of alternatives as he tries to return to football after leaving Bournemouth nearly a year ago.
The Celtic hierarchy is said to be impressed with Howe and may offer a package to entice him back into management.
Since Lennon’s exit from the club in February, the Hoops have been linked with several high-profile candidates, with John Kennedy acting as interim manager in the meantime.
Kennedy claimed earlier on Thursday that he had been offered no timeline for the arrival of a new boss or head coach.
Celtic is still planning to fill another role within their football department in the coming weeks, following the resignation of Head of Football Operations Nick Hammond on Wednesday.
Captain Scott Brown will depart for a player-coach job with Aberdeen at the end of the season, whilst Chief Executive Peter Lawwell will step down at the end of June, to be replaced by Dominic McKay, who joins from the Scottish Rugby Union.
Former Celtic midfielder Paul Lambert on Sky Sports:
“I think whoever goes into Celtic has a big job on their hands. It’s a fantastic football club, it’s worldwide and has pressures with it. If Eddie does get the job, I think it’s a good fit. He will know he has to win games, you don’t get away with many draws. There are loads of candidates out there to get what is an incredible job, but whoever gets it knows they have to win every week. It wouldn’t matter that Howe isn’t a fan of the club; as long as Celtic fans see the team winning. You won’t get given a year or two of grace, you have to win, but that’s the nature of the club and that’s what makes it a special club. Anyone who has managed or played there will tell you the same. It doesn’t matter if Barcelona or Bayern Munich come to town, you have to win. But whoever gets it right there, will be in for a great, great time. If you finish second, it’s virtually last, and the Celtic fans will let you know. Howe’s pedigree gives him that chance with it.”
