Martin O'Neill has left the door open to extending his Celtic tenure after masterminding a dramatic Scottish Premiership title triumph. The 74-year-old came out of retirement twice this season, first replacing Brendan Rodgers then returning after Wilfried Nancy's disastrous 33-day spell.

Celtic's 3-1 victory over Hearts at Parkhead secured their 14th crown in 15 seasons. O'Neill described feeling "rejuvenated" by the experience, telling reporters the club had given him life again after he was enjoying retirement in London just months ago. The manager credited players and supporters for energizing what he called "the most special place on earth."

Sky Sports pundit Chris Sutton called it O'Neill's greatest managerial achievement, praising how he transformed a stuttering side into champions with seven consecutive wins. Defender Alistair Johnston, back from injury for the run-in, hailed the "greatest league win of all time" and suggested Celtic should "build him a statue" for finding ways to win when it mattered most.

The focus now shifts to the Scottish Cup final against Dunfermline on May 23, where O'Neill will seek a double while weighing his long-term future. At 74, the toll of management remains a factor in any decision about staying beyond this remarkable rescue mission.
