What a £125m striker is actually worth

In September 2025 Newcastle sold Alexander Isak to Liverpool for a British-record fee of around £125m. In August he walks back out at St James’ Park, in a Liverpool shirt, for the 2026/27 opener. The number followed him, the way big numbers do. But there is a question hiding underneath it that the transfer market never quite answers, and a model answers first: what is a striker actually worth?

The fee is not the value

A fee is a price the market agreed on once, under pressure, with a selling club that did not want to sell and a buying club that decided it had to. It carries age, resale, scarcity, wages and status, all bundled into one headline figure. A model reads none of that. When Touchline simulates a match, it never sees a pound. It sees a rate: how many goals this team is likely to score, and how much this striker adds to that rate over the forward who would otherwise play. That difference, the goals he adds over a replacement-level forward, is the whole of his value to the model.

So the fee and the value are two different currencies. One is paid once, up front, and then forgotten by the pitch. The other is earned in ninety-minute instalments, goal by goal, over the length of a contract. The only honest way to compare them is to convert the fee into the currency the model actually uses.

Convert the fee into goals

The arithmetic is not complicated, which is rather the point. Take the fee, divide it by the goals. A striker who scores 20 league goals in a season has cost £6.25m for each one. Spread the same £125m across a five-year contract and that falls to £1.25m a goal, which sounds almost reasonable until you remember most strikers do not score 20 in a season, and fewer still do it five years running. Halve the output to a quiet ten-goal season and each goal doubles in price to £12.5m; a lean season near the bottom of the dial and the number stops meaning anything at all. Move the slider and watch the cost of a single goal swing from merely expensive to plainly absurd.

The shape of that curve is the argument. At the low end the cost per goal is a number no club would ever say out loud. At the elite end, the very top of the scoring charts, it settles into something a director of football could defend with a straight face. In between is the honest truth about a fee this size: £125m only makes sense at a level of output most strikers never reach. The market is not paying for the average season. It is paying for the ceiling, and betting the ceiling holds for years.

What the model would rather own

None of this says the transfer was wrong. Newcastle banked a record fee for a player at his peak, and Liverpool decided the goals were worth the ceiling. Both can be right. What the model insists on is a narrower claim it can defend on the pitch: it would rather own the argument about goals than the argument about the fee. When Isak lines up against his old club, Touchline will not nudge Liverpool’s number because he cost £125m. It will nudge it by however many goals he is expected to add, and not one goal more.
