The transfer market learns slower than the analysts think

Everyone assumes an edge in recruitment disappears the moment it is published, and the evidence from selling clubs says otherwise.

The standard story is tidy. Someone finds an undervalued type of player, buys a few cheaply, wins, writes a book, and within two seasons everybody else has copied the method and the discount is gone. Efficient markets, applied to footballers.

Football is not that market, and the reasons are structural rather than intellectual. A financial market has thousands of participants trading a homogeneous asset continuously with instant price discovery. A transfer market has a few dozen serious buyers, two windows a year, unique and non-substitutable assets, and prices set by negotiation between two clubs with wildly different urgency. That is not an environment where information propagates quickly.

Then add the agency problem, which does most of the work. The person deciding is rarely the person paying. A sporting director who signs a well-known player from a big league and fails has made a defensible mistake, and he keeps his job. The same man signing an unknown from a smaller league on the strength of a model and failing has made an indefensible one. The incentive is not to be right; it is to be wrong in a way nobody can criticise, and that incentive survives every analytics conference you can hold.

There is also the transmission problem. A club can hire an analyst who understands the edge perfectly and still fail to act on it, because acting requires a scout, a manager, a chief executive and an owner to align inside a two-week window while an agent shops the player elsewhere. Knowing is cheap. Executing is where clubs actually differ, and execution capability moves slowly because it is made of people and habits.

Which is why the same discounts keep showing up. Players from less fashionable leagues. Players just past a birthday that makes buyers nervous. Players whose statistical profile is good and whose highlight reel is dull, and highlight reels move directors more than anybody involved would admit.

The edge is not information any more. Half the industry has the same data from the same three suppliers.

The edge is being an organisation capable of doing an unpopular thing quickly, and there is no way to buy that in a window.
