A sell-on clause is a term in a football transfer contract that entitles the selling club to a percentage of any future transfer fee if the buying club later sells the player to someone else. The percentage usually falls between 10 and 25 percent. The original club has no say in whether or when the next sale happens; the clause simply guarantees a cut if it does. It exists because a club that develops a teenager and sells them cheaply would otherwise watch the player’s value multiply at another club and receive nothing from it.
How the Payment Is Calculated
Two formulas dominate, and the gap between them can be enormous.
A total-fee clause applies the agreed percentage to the entire fee the buying club receives on the next sale. If Club A negotiated a 20 percent sell-on and Club B later sells the player for £50 million, Club A receives £10 million. It does not matter what Club B originally paid.
A profit-based clause applies the percentage only to the difference between what Club B paid and what Club B receives. Using the same numbers, if Club B bought the player for £10 million and sold for £50 million, the profit is £40 million and the 20 percent share is £8 million. If Club B sells at a loss, nothing is owed. Buyers prefer this version because it caps their exposure, and the contract has to define exactly what counts as the original acquisition cost so there is nothing to argue about later.
Which formula applies comes down to leverage at the time of the first sale. A club selling a highly rated prospect can usually push for a total-fee clause. A club that needs to move a player quickly often cannot.
Deductions and Currency
Some contracts let the buying club subtract certain costs before the percentage is applied. Agent fees, legal costs, and other transaction expenses can shrink the base figure. If Club B pays £2 million in agent commissions on a £20 million sale and the contract allows deductions, the sell-on percentage might be calculated against £18 million. Whether deductions are permitted depends entirely on the original wording. Sellers negotiating the clause should push for language that applies the percentage to the gross fee.
Cross-border deals add exchange rate risk. A clause negotiated in euros can produce a very different payout when the resale happens in pounds or dollars years later. Some contracts fix the rate at the date of the original agreement; others use the rate on the date of the new transfer; more careful drafts peg the conversion to a specific benchmark or split the risk. When the contract says nothing, the rate at the time of payment usually applies.
What Triggers a Payment, and What Doesn’t
The common trigger is a straightforward permanent transfer: Club B sells the player to Club C for a fee, the deal is registered, and the sell-on obligation activates. A release clause works the same way. If another club meets the player’s buyout price, the resulting fee triggers the sell-on just like any negotiated transfer.
A loan with a mandatory purchase obligation is slightly more complex. The clause does not activate during the loan itself because no permanent transfer has happened. Once the purchase obligation kicks in and the deal converts, the payment becomes due. The timing matters because add-on payments and currency movements can shift the final number between the start of the loan and the conversion date.
The scenario that most often wipes out a sell-on clause is a free transfer. If the player’s contract at Club B runs down and they leave for nothing, there is no fee to take a percentage of, and the original club receives nothing. Clubs sitting on valuable sell-on rights have watched them evaporate this way. A heavily discounted sale produces the same problem in miniature: a nominal fee produces a nominal percentage, and under a profit-based clause a below-cost sale produces zero.
Indirect transfers can also create gaps. If a buying club restructures its ownership or routes the player’s registration through an intermediary entity without a traditional sale, whether the clause applies depends on how broadly “transfer” was defined. Careful drafting anticipates these workarounds.
Why Clubs Agree to Them
Accepting a sell-on clause is often the price a buyer pays for a lower upfront fee. A seller holding out for £15 million might take £10 million if a 20 percent sell-on sweetens the long-term picture. For the buyer, it is a bet: if the player does not appreciate much, the clause costs nothing; if the player becomes a star, the club still gets years of peak performance before paying a share of the eventual sale.
The clause is worth most on young players with high ceilings. A 15 percent cut of a 29-year-old’s next transfer is unlikely to produce much, because the next move will probably be at a lower fee or on a free. The same 15 percent attached to an 18-year-old can be worth millions if the development bet pays off.
Examples of Sell-On Payouts
When Everton sold John Stones to Manchester City for £47.5 million in 2016, Barnsley collected roughly £7.1 million from a 15 percent sell-on built into the original deal that took Stones to Everton. For a League One club, that was transformative money.
QPR’s 25 percent sell-on in Raheem Sterling’s contract produced around £11 million when Liverpool sold Sterling to Manchester City for £44 million. Arsenal inserted a sell-on when Cesc Fàbregas joined Barcelona and collected approximately £5 million when Barcelona sold him to Chelsea for £30 million. Chicago Fire stood to receive over $8 million from Jhon Durán’s reported $80 million move from Aston Villa to Al Nassr, having originally sold him for around $22 million.
Sell-On Clause vs. FIFA Solidarity Contribution
The sell-on clause is sometimes confused with FIFA’s solidarity contribution, but they are separate mechanisms. A sell-on clause is a privately negotiated term between two clubs. The solidarity contribution is a FIFA rule under Article 21 of the Regulations on the Status and Transfer of Players.
Under the solidarity mechanism, 5 percent of any transfer compensation paid for a player who moves during a contract is set aside and distributed to every club that contributed to the player’s training and education between the ages of 12 and 23. The buying club handles the distribution, proportioned by how many years each club trained the player during that window. This happens on every qualifying transfer, whether or not anyone negotiated a sell-on clause.1FIFA. FIFA Clearing House Regulations and Explanatory Notes
A sell-on clause is voluntary. It exists only if the clubs put it in the contract, benefits only the specific club that negotiated it, and carries whatever percentage the parties agreed on. A club can receive both a solidarity contribution and a sell-on payment from the same transfer, though the contract may specify whether the solidarity portion is deducted before the sell-on is calculated.
Anti-Embarrassment Clauses
A narrower relative of the sell-on clause is the anti-embarrassment clause, sometimes called a “super sell-on” informally. A standard sell-on applies indefinitely to any future sale. An anti-embarrassment clause typically covers only resales within one to three years of the original deal. It protects the seller from the specific scenario of watching an asset flip for a large profit almost immediately.
These clauses tend to carry higher percentages than standard sell-on provisions because they cover a shorter, more acute window. They appear most often where a seller is forced into a low price by financial pressure and wants protection against an opportunistic quick resale. Once the restricted period expires, the obligation disappears entirely, unlike a standard sell-on, which remains active for any subsequent transfer during the player’s career.
When the Payout Is Disputed
Most disputes over sell-on payments come down to what counts toward the sale price. Modern deals are rarely a single number. Performance bonuses, appearance-based add-ons, and installment structures all create room for disagreement. If Club B sells a player for £30 million with another £10 million in add-ons that may or may not vest, the sell-on could be calculated on £30 million, £40 million, or something in between depending on how the contract is worded and whether the add-ons eventually trigger.
When a club refuses to pay or disputes the amount, the matter typically goes to FIFA’s Football Tribunal through the Dispute Resolution Chamber. Orders can include payment of the outstanding sum plus interest, and clubs that ignore a ruling risk sanctions including a ban on registering new players. Clubs within the same national association may also have access to domestic arbitration, depending on federation rules. Disputes between clubs in different countries default to FIFA’s jurisdiction. Clear drafting at the outset prevents most of these problems, but not every contract anticipates every scenario.
