Republic of Ireland skipper John O'Shea is confident manager Martin O'Neill will more than make up for the loss of Roy Keane if he lands the Celtic job.
O'Neill's preparations for Saturday's friendly against World Cup finalists Italy have been carried out against the background of a sideshow which has seen his 42-year-old assistant installed as favourite for the vacant job at Parkhead after holding informal talks with his former club.
However, should Keane be appointed - Celtic have insisted he is only one of a series of candidates to replace Neil Lennon - O'Shea has no doubts that O'Neill's expertise and personality would fill the void he would leave behind.
The 33-year-old Sunderland defender said: "Ah well look, the manager we have is very, very important and very, very talented and fortunately we will have time for the manager, if it does happen, to adjust his backroom team accordingly for the forthcoming qualification games.
"In that sense, we are lucky that he will have a bit of time to adjust. He has brought Steve Walford and Steve Guppy in this week as well, so we are fortunate we have the time beforehand, if it does happen, to adjust.
"Believe me, the manager can do it himself as well."
"It's something I'm sure he would really, really enjoy and look forward to and relish the challenge of managing a fantastic club like Celtic."
Asked if his former team-mate had said anything to the players, O'Shea said: "No, no, no. Obviously the lads have been trying to get a few hints here and there, but he's kept a good poker face."
Keane will travel to London for the clash with the Italians at Craven Cottage, but whether he boards the plane for the United States next Wednesday with further friendlies against Costa Rica and Portugal remains to be seen.
O'Shea admits he fears the worst, but is confident Ireland would cope with the loss of a man who has proved hugely inspirational since his addition to the backroom staff.
The defender added when quizzed on his gut feeling: "It looks very much like it now. Slowly but surely, it has snowballed into having talks with Celtic, so I would be very surprised if it doesn't get across the line.
"If it does happen, it's one of the clubs around the world that was going to entice him back into management and away from his current job.
"It's something I'm sure he would really, really enjoy and look forward to and relish the challenge of managing a fantastic club like Celtic. But let's wait and see if it does happen.
"As the manager said, we would be very disappointed because we know what a fantastic character he is to have fighting for us on our side going into matches."
O'Neill admits he is yet to broach the subject of whether or not Keane could combine the two jobs, but O'Shea sees no reason why it could not be done.
He said: "That's something for people other than myself to talk about, but I can't see why he couldn't do it.
"But I'm sure Celtic and the FAI [Football Association of Ireland] would maybe prefer it to be one way or the other, but hey, things have been done like that in the past, so why can't it be done in the future?"
