Martin O'Neill disclosed that Police Scotland delivered a "general behaviour" advisory to Celtic in the run‑up to Sunday’s League Cup quarter‑final against Rangers at Ibrox. The directive comes amid a contentious ticket‑allocation dispute that has seen authorities decide that no Celtic supporters will be permitted inside the 50,000‑seat arena for the match. The disagreement over ticket distribution is rooted in the fallout from the previous Old Firm encounter in March, when a chaotic scene unfolded at Govan.

That game, which ended goalless after 120 minutes, was ultimately decided by a penalty shoot‑out that saw Celtic lift the Scottish Gas Scottish Cup quarter‑final. The disorderly conduct displayed by fans on both sides prompted the Scottish football authorities to impose strict sanctions on the two Glasgow giants. Both clubs have now been instructed to hold their forthcoming home fixtures in the Scottish Cup behind closed doors, meaning no spectators will be admitted.

In addition, each side has been hit with a £100,000 compensation charge, which will be paid to the opponent that is drawn as the away team for their next Scottish Cup tie. The financial penalty is intended to cover the loss of gate receipts and to act as a deterrent against future disturbances.

At 74 years old, O'Neill admitted that the prospect of playing a high‑profile derby without the roar of the Celtic faithful will feel "a bit strange," yet he also expressed a mixture of nerves and excitement. "It's a great fixture, and I'm looking forward to it," he said, adding that the police visit was a timely reminder of the responsibilities that come with such a passionate fan base. During a brief fifteen‑minute meeting with the police, O'Neill recapped the advice he received. "They gave us a reminder about our behaviour on and off the pitch.

It's a good thing – a necessary reminder given the recent incidents," he explained. He emphasized that the focus was not only on preventing physical altercations but also on curbing excessive celebrations that could be misinterpreted as provocations. "We don't want any punch‑ups, and we certainly don't want over‑the‑top celebrations that could inflame tensions," he added. O'Neill also reflected on the broader context of recent fixtures, noting that the clubs have been under intense scrutiny after a series of incidents involving supporters.

"The behaviour we exhibit now will set the tone for future games. If we can keep things under control, it will be something to celebrate," he said, underscoring the delicate balance between passion and discipline. The manager also touched on squad matters ahead of the clash.

He confirmed that midfielder Mika Baur, who missed Friday's training due to a minor knock, will be back on the training pitch on Saturday. However, O'Neill has yet to decide whether newly signed goalkeeper Sam Johnstone will retain his starting spot or be replaced by Viljami Sinisalo, who began the season as Celtic's first‑choice keeper.

Johnstone, an experienced England international currently on loan from Wolverhampton Wanderers, made his Celtic debut in a 1‑0 Scottish Premiership victory over St Johnstone at McDiarmid Park. O'Neill remained cautious about committing to a definitive choice, stating, "I haven't made up my mind yet. It's about assessing what Sam can bring to the team." He praised Sinisalo for his performances, noting that the Finnish keeper has "done exceptionally well" for the Hoops.

"We have the luxury of having both options. Viljami has been fantastic, and now it's an opportunity to see how Sam performs in training and potentially in the match," O'Neill explained.

He added that a goalkeeper's abilities can evolve dramatically over a few years, and he wants to give both players a fair assessment before making a final decision. Beyond the immediate tactical considerations, O'Neill highlighted the broader significance of the Old Firm rivalry. The fixture is more than just a cup tie; it is a cultural event that draws attention from across Scotland and beyond. The heightened security measures and the police warning underline the responsibility that clubs and supporters share in maintaining public order while preserving the passionate atmosphere that makes the derby unique.

In the meantime, fans are being encouraged to stay engaged through alternative channels. The club's official website and social media platforms will provide live updates, highlights, and post‑match analysis.

Supporters who cannot attend the match in person are also invited to participate in promotional activities, such as the "Super 6" competition, which offers a chance to win £250,000 with a free entry. Overall, the upcoming quarter‑final promises to be a tightly contested encounter, played under the watchful eye of law enforcement and with the added pressure of a fan‑free stadium. Celtic's management is focused on ensuring that the team remains disciplined, both on the field and in its interactions with the broader community, while still striving for a victory that would add another chapter to the storied Old Firm legacy.
