The history books show that even successful Celtic managers have their own shelf lives. Martin O’Neill stayed for five years in the east end of Glasgow. Gordon Strachan and Neil Lennon bowed out after four.
For a Celtic support presently in raptures at the way Brendan Rodgers has transformed their club, such trends are becoming increasingly relevant.
With a sixth successive title in the post and the gap between their side and the chasing pack only widening, the capturing of what would be a record 10th flag now seems possible. The question no longer being asked in whispers is whether the current manager will still be on board if and when that day dawns.
