Keane has impressed for Celtic, scoring eight goals so far.
Jordan told the Sunday Herald: “Without a doubt [Keane will return], he’s the captain.
“Harry [Redknapp] brought him back here and he was a major player in getting us out of trouble last season, not just on the pitch, but in the dressing room as well.
“He was an influential guy, he’s a leader, and there’s not many of them going about. It wasn’t just the player, it was the person we wanted.”
