Where are Celtic & O'Neill a year after Rodgers exit?

O'Neill's win percentage of nearly 75% in his latest spell is similar to his club record level during his trophy-laden five years in charge to 2005.

However, the recent 7-1 thrashing of Hearts apart, performances this season have largely left the Celtic support underwhelmed, while it is results in Europe - and two defeats in a week by city rivals Rangers - that have caused most alarm.

When Rodgers left, Celtic had won eight games, drawn four and lost four overall at the start of last season.

This season, they have won 11 and lost six, but on their way to a Champions League exit and to the foot of the Europa League after three games, they have suffered heavy defeats against LASK, Ferencvaros and Benfica.
