IK Sirius leads the Swedish top tier in Transfer KPI

Structure and development sounds boring. But that's how clubs win.

Nobody wants to talk about squad structure on a matchday. It doesn't trend. It doesn't generate takes.

But here is a fact worth sitting with: IK Sirius FK have had the highest average transfer-KPI in the Swedish top tier over the past five years. They currently lead the table. In Portugal, FC Porto have had the highest over the same period. They won the league. We don't think that's a coincidence.

"KPIs" gets thrown around a lot in Swedish football discourse, almost a buzzword, something clubs say to sound modern, something pundits roll their eyes at. We get it. Most metrics cited in press conferences don't survive contact with a full season of data.

Our transfer-KPI measures whether a club has created the structures necessary to build a stronger club over time. Sustained high scores tell you a club has the structure needed to keep performing. It is our verdict on whether a club is developing or aiming for short-term results no matter the cost.

When you set each club's five-year average transfer-KPI against their current points per game, a clear pattern emerges. In the Swedish top tier the correlation sits at r ≈ 0.89. IK Sirius FK leads both dimensions, as do BK Häcken, Hammarby Fotboll AB and IF Elfsborg. In the Portuguese top tier the correlation is even stronger at r ≈ 0.92. This relationship is strongest in development-driven leagues, where building a sellable squad and winning tend to go hand in hand.

There are causality questions worth acknowledging. Clubs with above-average wage bills do tend to score higher, but there are plenty of exceptions. IK Sirius FK is the most striking: a modest budget, consistently one of the most sellable squads in the league. It is also worth asking whether clubs that structure their squads well are simply better at structuring everything else too, recruitment, development, contract management, in ways that make them more likely to win regardless of the metric you use.

AIK Fotboll, listed on Nasdaq First North, has started including our transfer-KPI in their quarterly earnings reports. They currently hold the second highest score in the Swedish top tier after IK Sirius FK and one of the highest in Europe. When you have public shareholders, you need a forward-looking indicator of club development. We understand completely why they made that call.

The league-wide picture is also moving in the right direction. Average transfer-KPI in the Swedish top tier has grown from 17.4 in 2021 to 27.7 in 2026, up 59% in five years. Among the leagues we track, it is now the best structured for future performance relative to size. That doesn't happen by accident.

Boring? Maybe. Effective? The data says yes, and it's not boring to win.
