Old Firm, Hearts and the Data Gap at Parkhead

There were 51,212 people inside Ibrox. Three goals were scored: Dan Neil with a brace, Kevin Kelsy finishing in the second half. The Scottish League Cup stayed with the club managed by Derek McInnes. When I laid out every published data point from that match as a table, the table had three rows: the attendance, the list of scorers, and four adjectives describing the football — “unbending physical commitment”, “lots of sprinting”, “patchy”. No xG. No PPDA. Not a single distance-covered figure.

Twelve reports, each written differently, stacked on top of one another tell one story: this team wins through running. But that story was told by human eyes, not by instruments. To an investigator, that is exactly where the money usually hides — and exactly where a verdict is easiest to overturn.

Another Old Firm derby is coming, this time at Parkhead. The interesting part is not the two Glasgow names. In the table, between Celtic and Rangers, sits a third club: Hearts. A force wedged between two giants is rare, and it changes the meaning of this fixture entirely. A Rangers win is not simply three points taken from a direct rival; it reorders a group of three. The next meeting between the sides is already fixed for 3 January, which means this will be the last encounter for months. The narrative weight of every result is multiplied accordingly.

On the continental front, the balance tilts clearly: Rangers are out of Europe after playoff defeats, while Celtic retain a Europa League tie against Ferencváros. In Scottish football, European participation is the real dividing line of financial tier — prize money, matchday income, coefficient. Losing a European place narrows room to manoeuvre in the transfer market.

But I want to return to the data gap, because that is the part worth arguing about.

The playing style under McInnes is described as a nascent identity built on physical commitment and running volume. This is a transition-oriented template that prioritises running power over ball control. It is sustainable against open opponents willing to trade blows, but it can be smothered by a low block that concedes possession. The source report itself concedes the quality of the football “may have been patchy” — a roundabout way of saying chances came from intensity, second balls and set pieces rather than structured build-up.

Based on my experience watching these matches, a team that runs a lot without publishing pressing data falls into one of two groups: either the pressing is real and the data simply has not been mined, or the running is loud without pressure — running to look committed. Telling the two apart requires exactly one number: passes allowed per defensive action. The report does not have it. So the conclusion must be downgraded to directional, not final.

The positive signal is genuine: three goals came from two different sources, a midfielder’s brace and a striker’s finish. That is a distributed scoring model, healthier than single-point dependency. But the sample is one match. One match is not a trend; it is a data point.

The derby context adds its own tactical layer. Celtic are at home, and after a bad week — losing the League Cup, then losing in Europe — they are obliged to control the ball and push bodies forward. An opponent forced into that posture is precisely the prey a McInnes energy-and-counter model is designed to hunt.

Alongside that sits psychological pressure. McInnes has just bought time and credibility with the cup itself. O’Neill enters this match in a visibly cantankerous state. A manager’s demeanour is a leading indicator of internal strain: it tends to transmit into player body language and risk tolerance. Even so, I have to state plainly what the source analysis does not: the coach-to-club mapping in that document does not match officially published personnel data. The attribution must be verified before it explains anything.

The counter-intuitive part is here. The story being told is “Rangers buoyant, Celtic in crisis”. That framing has a results basis but lacks data depth. There is a second reading, less flattering and therefore less chosen: Hearts sitting between the two Glasgow clubs does not necessarily reflect Hearts over-performing. It may reflect both big clubs dropping more points than usual. One dataset, two readings, and the second one puts pressure precisely on the people being painted in bright colours.

The “one-match hero” story deserves fair treatment too. Neil and Kelsy are being pushed forward as men of the week. On a single sample, that is a projected expectation that can reverse inside ninety minutes. An athlete denied it three times. His data file has spoken since the fourth — but here, nobody has bothered to open a file at all.

What is worth tracking, then, is not who wins the derby. What is worth tracking is whether, after this match, the two coaching staffs publish sprint-distance and pressing figures. A team that runs on its own strength has no reason to hide the number. A team running on something else always has a reason not to publish it.
