Martin O’Neill admits Celtic’s fixture load could catch up with them as they head into a stretch that may shape the title race.

Ten games in roughly 40 days leaves little margin for error. The volume alone brings risk, especially with a trip to Rugby Park on Sunday looming large.

Looking back on similar runs during his first spell in charge back in the early 2000s, O’Neill recalled how relentless it felt during the famous run to Seville.

“It was just one game after another, after another. There didn’t seem any break,” he told Celtic TV .

That sense of momentum, and fatigue, is back.

Celtic arrive at Kilmarnock knowing the stakes. A win at Rugby Park would not just be three points. It would apply pressure in the title race and reinforce the message that they can handle the strain. Drop points, and the fixture pile-up starts to look less manageable.

O’Neill has not ignored the danger.

“I know that in many aspects that these extra games, they might be the undoing of us. But that’s the whole idea of getting a few extra bodies in.”

There is no glossing over the workload. The manager accepts the trade-off. If you compete on multiple fronts, the calendar tightens and recovery time shrinks.

That is why January additions such as Alex Oxlade-Chamberlain will be essential. They were signed for nights and afternoons like this, when legs tire and rotation becomes necessity rather than preference.

Sports science offers more support than it once did. Recovery and rotation are mapped out in detail. Even so, the schedule is unforgiving.

Still, O’Neill is not dramatising it. “It is what it is. Let’s just get on with it.”

Sunday at Rugby Park feels pivotal. Navigate it well, and Celtic strengthen their hand in the title race heading into a demanding run. With Hearts and Rangers playing later on Sunday, at least one of them will drop points, if Celtic already have their win in the bag, it would be a big moment.
