Former Celtic midfielder Stiliyan Petrov also warned that Celtic cannot afford complacency heading into next season: Rangers are expected to strengthen, Hearts will push again, and the club will need to compete on both the domestic and European fronts. "Last season, they got away with it," Petrov noted. "Next season will be a big challenge."
O'Neill himself acknowledged after the Scottish Cup final that Celtic might consider appointing someone younger. Instead, he takes charge once more — targeting further silverware and tasked with ensuring Celtic's era of dominance endures.
