Brendan Rodgers' second two-year tenure as Celtic manager concluded following a 3-1 loss at Hearts, which saw his side trail by eight points after nine matches.
At the start of last season, when Rodgers departed, the team had recorded eight wins, four draws and four defeats.
Twelve months later, Martin O'Neill remains in charge, having completed two separate spells with 33 games managed under Wilfried Nancy interspersed between them.
The club secured its 56th league title and fifth consecutive championship after Rodgers' Northern Irish colleague overturned the Hearts lead to win at Celtic Park.
This season's campaign has seen O'Neill's side lose only one of ten league fixtures, with twenty-five goals scored against just six conceded.
Their win percentage in this latest period mirrors their record from the five years leading up to 2005.
Despite the recent seven-goal victory over Hearts, match quality has largely disappointed supporters, with two defeats against Rangers within a week raising concerns.
European competition and results against city rivals have been identified as primary sources of anxiety for fans.
