Obligation to Buy: When a Transfer Is Paid For in Time, Not Money

At 1:40 in the morning on August 13, 2026, on the screen of a small office on the edge of a second-division German city, there is a spreadsheet with two columns. The left column lists euros. The right column lists days. The man sitting in front of it is the club's sporting director, and he reads the right column first, top to bottom, as slowly as if he were reading a contract.

Three weeks earlier, his twenty-two-year-old right-back came on in the seventy-first minute of a match with nothing left to play for. The stands were half empty. Inside the stadium, nobody noticed. But in another office six hundred kilometres away, a line in a database had just changed colour: the twentieth appearance. The clause triggered. The obligation to buy became real, and that small club had just sold a human being for a string of numbers to be paid over four years.

People still say football is decided by money. In this transfer window, what decides most of it is the calendar.

Nuremberg 2026 taught me that real talent does not need the spotlight, it weeps in the dark. It took me years to understand that the second half of that sentence also applies to contracts: the most expensive part always sits in an annex, where nobody shines a light.

An instrument becomes the standard

The loan with an obligation to buy was born as an accounting solution and became the common language of the market. On paper, the receiving club pays a small loan fee and commits to buy once one or several conditions are met: appearances, minutes played, the team's final position, or simply a date. In substance, it is a completed transaction recognised late.

Juventus industrialised the instrument. In October 2026, Federico Chiesa left Fiorentina for Turin on a two-season loan for 10 million euros, with an obligation to buy at 40 million euros plus up to 10 million in add-ons. That same year, Weston McKennie arrived from Schalke on a 4.5 million euro loan fee with an 18.5 million euro obligation. In August 2026, Manuel Locatelli left Sassuolo for a 2 million euro loan fee and a 25 million euro obligation.

Read those three figures in a row and a pattern appears: the big club still has the money, it simply wants to spend it in a different year.

AC Milan walked the same road with Fikayo Tomori, loaned from Chelsea in January 2026 on a modest fee with a purchase option around 28 million euros, later activated. By the middle of the decade the instrument was no longer an Italian speciality. It appeared in England, in Spain, in deals where the seller needed revenue and the buyer needed time.

Why time became an asset

Financial rules turned time into an asset with a price. UEFA applies a squad cost ratio on a phased schedule: 90 per cent in 2026/24, 80 per cent in 2026/25 and 70 per cent from 2026/26. The numerator covers player wages, contract amortisation and agent fees; the denominator is revenue. The Premier League runs a parallel sustainability rule with an allowed loss of roughly 105 million pounds over three years.

In other words, a transfer fee does not land on the books in one hit. It is spread evenly across the contract years. A 50 million euro deal signed for five years creates a cost of 10 million euros per season. If the first season is a loan year with the obligation not yet triggered, that amortisation has not started. The buying club gets twelve extra months for its revenue to catch up with its cost.

That is the whole trick. Everything else is just legalising it in the language of law.

On the selling side, the story is different. Under international accounting standards, revenue is recognised only when control of the asset has transferred. An obligation to buy that depends on a condition that has not yet occurred may not be enough to book. Sassuolo sold Locatelli in a deal whose total value was far higher than the cash they received immediately, yet in the accounts that large sum surfaced only milestone by milestone.

Meanwhile, the small club has to replace the player at once, in cash, in a market where prices wait for nobody.

Money arrives late, costs arrive early

Even when the obligation is triggered on time, the money does not arrive in one payment. Instalments over three to five years are standard practice. A 25 million euro deal may pay 8 million in the first year with the rest spread out. The selling club receives 8 million and must find a replacement striker costing 12 million, paid up front.

That four million euro gap does not sit on anyone's balance sheet. It sits in corridors, in phone calls at midnight, in a coach forced to use a nineteen-year-old in a position his team is not ready for.

One more layer is usually skimmed over: the sell-on clause. When Manchester City sold Jadon Sancho to Borussia Dortmund, the contract kept a percentage of any future transfer. In July 2026, Sancho moved from Dortmund to Manchester United for a fee of around 73 million pounds, and City received roughly 11 million pounds under a sell-on reported at 15 per cent. For an academy, that is a beautiful model. For a small club buying players elsewhere, a sell-on clause is a tax on its own future.

There is a detail the spreadsheet never shows: agent fees. Representatives are paid at the moment of the transaction, not at the moment of recovery. The more complex the structure, the more parties benefit, while the party carrying the final risk always sits on the side with the smallest revenue. FIFA's attempt to cap agent commissions from 2026 was blocked in several European countries, and that says a great deal about who holds the pen in the drafting room.

Germany does the opposite, and that is deliberate

The Bundesliga sits almost outside this storm. The reason is not naivety. It is three rigid structures.

The first is the 50+1 rule, which forces members to keep control of the club and blocks outside capital from buying sporting control. The second is the Bundesliga licensing process, requiring every club to prove liquidity for a full season before the season begins. The third is the revenue gap. German domestic broadcast rights for 2026/26 to 2028/29 are worth around 1.121 billion euros per season, while the Premier League collects around 1.67 billion pounds per season from the UK market alone.

In short: German clubs do not have much money to spend in advance, and the rules do not let them spend money they may never have.

That is why Bayern Munich buys in cash, and why Bayer Leverkusen built a very different model: buy cheap, develop, sell high. Kai Havertz left Leverkusen for Chelsea in 2026 in a deal that could reach 80 million euros with add-ons. Florian Wirtz left Leverkusen for Liverpool in 2026 at a fee recorded at the British record threshold. There was no obligation to buy in either deal. There was a club selling at the right moment and a club that had the money.

That boredom is the strength. A league where every club knows in March how much money it will have may be less thrilling on the news, but it does not produce summers of despair.

The counter-intuitive point: what is being sold is not the player

I used to think the obligation to buy was how big clubs squeeze small ones. After several seasons of watching, I think that diagnosis misses. Big clubs only buy what small clubs are selling. And what is being sold is not the player. It is the interval between the moment the deal is signed and the moment the money is paid.

Sellers agree to sell that interval because they need a figure to appear in a report. A president needs to tell his board he sold a player for 25 million euros. That the 25 million arrives over four years, and that transfer inflation will eat part of it, is a detail nobody puts in the press release.

Sell-on clauses work on the same logic. They are sold as a reward for the future, when in reality they are a risk-sharing arrangement the small club is never compensated for if the player fails.

Then comes the sporting risk that appears in no spreadsheet at all. If the player suffers a serious injury during the loan and the condition is not met, he returns to his parent club with a lost season, a reduced value and a contract about to expire. The small club loses the player, the money and its bargaining power.

There is a flip side too. When a clause is triggered by appearances, the decision to send a player on in the eighty-first minute becomes a financial decision rather than a football one. The coach knows it. The player knows it. And in the dressing room, a twenty-two-year-old learns the first lesson of the trade: his value is measured by a line of data in an office he has never set foot in.

In this profession, I learned that delay is never neutral. Hanging a goal on a VAR screen for two minutes is enough to cool what just happened on the pitch, because a moment lived is not the same as a moment confirmed. Money is the same. A euro paid four years late does not keep the strength of a euro paid today, and the club receiving the later payment is always the club without the option.

Three recurring scenarios

In the notes I have kept across several seasons, most of these deals fall into three situations.

The best case: the player plays enough games, the obligation triggers on time, the selling club receives the full sum, and everyone calls it a smart deal. This case is the minority.

The middle case: the condition triggers but a season late, the seller's cash flow breaks rhythm, and the club takes a short-term loan to pay wages while waiting for the first instalment. Nobody writes about this case because it has no headline.

The worst case: the condition is never met. The player returns, his contract has one year left, his market value halves, and the small club is forced to sell cheaply in the final window before losing him for nothing. This is the scenario that generates most of the losses nobody labels as losses.

Those three scenarios are not equal in probability. But they are equal in consequence, and the small club carries all three.

Where Vietnamese football stands

Looking from Munich towards the V.League, I see the same trap in a smaller form. Vietnamese clubs also live on one or two deals a season, also loan out young players to trim the wage bill, and also record transfer success as a headline number. The difference is that no authority requires them to prove liquidity for a full season before the season starts.

There is a paradox I have observed in both football cultures: small clubs raise players, big clubs harvest them, and the reward for that upbringing is often paid as a percentage of a future deal nobody controls. It is a way of paying in hope instead of money.

The lesson from Germany is not to copy tactics, nor to dream of a large broadcast contract. The lesson is a boring administrative procedure: force clubs to prove they have money until November before letting them play in August. A licensing system strict enough would automatically erase most contracts that only look good on paper.

What I have seen over years of walking through small grounds in both countries is this: the club that survives is not the one that sells players best, but the one whose cash flow does not depend on the calendar of a single deal.

Closing

If in the next transfer window a small European club answers a 30 million euro offer with a question about the payment schedule instead of nodding at the figure, I will write about them before any of the big outlets. And if one day in the V.League a club refuses to sell a young player because the money would arrive too slowly against the cost of replacement, that will be a sign that football there has begun to grow up.

Real talent does not need the spotlight. It weeps in the dark. But a mature football culture is one that knows where to switch the light on: where the spreadsheet is, where the annex is, where the people sit reading the date column while the whole world stares only at the money column.
