Former Chelsea star Andy Townsend is backing Roy Keane for the Celtic job.
Manchester United legend Keane is in talks with Celtic.
"I've always felt that Roy had the ability to be a top manager and I genuinely still feel that," Townsend told the Sunday World.
"Keano has still got a bit of unfinished business as a manager. It wouldn't surprise me if a big club came his way.
"I don't know what direction Celtic are looking to go down, but I think he could be someone who goes in there and shakes things up.
"With Steven Gerrard in charge of Rangers and given his Liverpool connections, if Keano goes into Celtic with his Manchester United past, it would certainly make for great viewing in the Friday press conferences every week."
