Celtic manager Martin O'Neill has declared he remains addicted to the intensity of Old Firm derbies as his side prepare to face Rangers at Ibrox in tomorrow's Premier Sports Cup quarter-final.
The 74-year-old manager revealed that despite the pressure and relentless abuse from 50,000 hostile supporters, he still experiences a surge of energy ahead of the Glasgow derby. He confirmed his primary objective is to navigate an upcoming three-match week unbeaten across three separate competitions.
Tomorrow's quarter-final match at Ibrox Stadium represents the first fixture in a high-stakes double-header against Rangers, with a Scottish Premiership clash scheduled at Celtic Park next weekend. Sandwiched between the two derby matches, Celtic will open their Europa League campaign against Hungarian champions Ferencvaros in Glasgow next Thursday.
The Old Firm derby is the historic title given to matches between Celtic and Rangers, the two most successful football clubs in Scotland. First contested in 1888, the rivalry is renowned worldwide for its intense passion, cultural significance, and relentless scrutiny across the city of Glasgow.
Reflecting on his past experiences in the fixture, O'Neill recalled his first taste of derby day quarter of a century ago in August 2000, when his Celtic side recorded a famous 6-2 victory over Rangers at Celtic Park. However, his second derby proved far more painful when Celtic suffered a heavy 5-1 defeat at Ibrox.
"The second one wasn't that good," reflected the 74-year-old. "We got mauled, absolutely bleached 5-1 at Ibrox. I think we drew 0-0 with Hibs on the Wednesday afterwards, so we actually dropped five points in two games. If those things had happened in the first couple of games at the start of the season, I don't think I would be around to tell you about it."
Addressing opposite manager Derek McInnes, O'Neill noted that while tomorrow may mark McInnes's first derby as a manager, the former midfielder is steeped in Rangers tradition from his playing days. O'Neill also noted the 25th anniversary of 9/11, recalling that he was preparing Celtic for a Champions League fixture against Norwegian side Rosenborg when news of the attacks broke in 2001.
McInnes spent four years as a player at Ibrox between 1999 and 2003, giving him extensive personal experience of the Glasgow derby environment. Hibernian, commonly known as Hibs, are based in Edinburgh and represent one of Scotland's traditional top-flight clubs alongside the Glasgow powers.

The Psychological Compulsion of Glasgow Derbies
Describing the unique emotional strain of managing in Glasgow, O'Neill admitted he continues to worry constantly before matches and never expected to be taking charge of another derby at this stage of his career. "Did I expect to be sitting here talking about another Old Firm game? Absolutely not," O'Neill said. "I sometimes do think, what am I doing here?!"
O'Neill explained that the fixture becomes addictive, creating feelings of pure euphoria or ultimate disappointment depending on the result. "Will I be glad to see the back of it? Well, yes, I will," O'Neill said. "I'm desperate for that coffee on the Kings Road again, I really am. I'd like to know what normal life is like again, because this is not normal. No, I shouldn't say that. There's part of me, there must be part of me, that loves it. But did this type of fixture make me want to stay? No, it made me think the opposite. Absolutely."
O'Neill revealed that his daughter reminded him that for every person who loves him, there are a million who hate him, leaving him feeling outnumbered at away grounds. "Do I want to go to Ibrox again and hear all that abuse behind me? No, no, absolutely not," O'Neill said. "My daughter, who is much more clever than me, said for every person that loves you there's a million that hate you. I keep that in mind. There will be thousands behind me chanting something or other."

Season Defining Double-Headers and Mental Impact
O'Neill emphasised that back-to-back derby matches can exert a powerful psychological influence on both clubs. He recalled early beliefs that losing all four league derbies was acceptable if a team still won the league title, but insisted neither Celtic nor Rangers supporters would tolerate that mindset today, making derby results critical to overall momentum.
"I always used to feel that Old Firm matches, particularly the league games, could define a season," O'Neill continued. "I used to think that if you lost all four derbies but still won the league, then that's fine. I don't think Celtic fans would be having that now. I don't think Rangers fans would be having it either. I was soon disavowed of that particular thought. What I'm saying is that it would be highly unlikely to win the league if you had lost all four games against Rangers and vice versa."
To illustrate the knock-on effect when teams meet twice in a week, O'Neill pointed to last season's clashes. "These games can have a knock-on effect psychologically when you play each other twice in the space of a week," O'Neill said. "I think you saw that last season when we fought back from 2-0 down to get a draw, and then beat them in the cup the following week. Yes, these games can influence each other."

Tactical Options and Selection Conundrums
Ahead of tomorrow's match, O'Neill faces a key selection decision in his forward line, with fit-again striker Kasper Hogh likely to lead the attack. Winger Camilo Duran is also certain to feature following an impressive start to the campaign, leaving one position on the opposite wing up for grabs.
While O'Neill has frequently deployed a 4-3-3 formation, he disclosed that he is considering a switch to a 3-5-2 system featuring a back three. "I think he can play as a centre-forward or just off the centre-forward," O'Neill said when asked about Duran's best position. "I think those are probably his best positions. He played wide against Kilmarnock and I thought he was excellent. But I think he likes to be up there centrally and trying to score a few goals. It's up to us now to coach him in a few different positions over the season and make sure we really get the best out of him."
O'Neill also praised Hogh's contribution, noting that the striker was good "the other night" and will become a major asset following the international break. "We've got three huge games over the course of the next week in three different competitions," O'Neill said. "It would be nice to go through this period unbeaten if we possibly can. By the time we then come back from the international break, Kasper will be a big player for us. In all honesty, I hadn't realised how many games he had played prior to joining us due to how the season works over in Norway."
Ferencvaros, based in Budapest, are Hungary's most successful club and regular competitors in European group stage football. Kilmarnock compete alongside Celtic in the Scottish Premiership, operating out of Rugby Park in Ayrshire. Norway's top division, Eliteserien, operates on a spring-to-autumn calendar year structure, meaning players arriving from Norwegian clubs often carry a heavy competitive workload from earlier in the year.
