Celtic’s dominance over Rangers in the 21st century has been nothing short of remarkable. Under the leadership of Martin O’Neill, the club saw a complete transformation that led to their unparalleled success in Scottish football over the past 25 years.
O’Neill’s tenure at Parkhead saw the arrival of key players like Chris Sutton, John Hartson, and Neil Lennon, as well as the development of Henrik Larsson into a world-class striker. During his time at the helm, Celtic secured three league titles, three Scottish Cups, and two League Cups, firmly establishing themselves as the top team in Scotland.

Rangers, on the other hand, struggled to compete with Celtic during O’Neill’s reign, with former player Egil Ostenstad attributing his failure at the club to Celtic’s overwhelming success. Ostenstad’s brief stint at Rangers coincided with Celtic’s dominance in the league and cup competitions, making it challenging for him to make an impact at Ibrox.

Since O’Neill revolutionized Celtic in 2000, the club has amassed an impressive collection of domestic trophies, including 19 league titles, 12 Scottish Cups, and 11 League Cups. With a total of 42 trophies in 25 years, Celtic’s dominance in Scottish football is truly unmatched.
As Celtic continues to thrive, it’s likely that more Rangers players will feel the sting of their fierce rivalry in the coming years. The legacy of O’Neill’s success at Parkhead is sure to endure for decades to come.
