Martin O’Neill admits he does not know if he would “have the energy” to stay on as Celtic boss past the end of the season.

The 73-year-old has returned to the Glasgow club following the departure of Wilfried Nancy, 33 days after making way for the Frenchman following an interim spell in which he won seven out of eight matches.
