What is sell on clauses work? Explained

By Arasi Rex · Updated 14 August 2026 · 5 min read

Sell‑on clauses let clubs lock a future fee into a transfer. They are a contractual tool that promises a percentage of any future resale fee to the original club. While they look like a safety net, the real benefit often lies in the potential upside when a player thrives elsewhere.

The mechanism of sell‑on clauses

Sell‑on clauses are added to a transfer agreement at the time a player moves from one club to another. The clause specifies a fixed percentage of the fee that will be paid to the selling club when the new club sells the player again. The percentage is agreed upon by both parties and is part of the final contract.

At the moment of the second transfer, the selling club receives the agreed percentage of the new fee, regardless of how the first fee was structured or any performance‑based bonuses that may have been paid. The clause is enforced automatically; no additional negotiation is required unless the clubs agree to amend the terms.

The clause is valuable because it turns a one‑off payment into a potential long‑term income stream. Clubs that sell a promising youngster often use a sell‑on clause to secure future revenue if the player’s market value grows.

History and evolution

Sell‑on clauses have existed in football for decades, but their use became more prominent after the Premier League was created in 1992. The new league, with 20 clubs playing 38 matches each, introduced higher revenues and a greater incentive for clubs to protect future earnings.

Initially, sell‑on clauses were simple: a flat percentage of the resale fee. Over time, clubs began to craft more sophisticated clauses that included trigger points, such as a minimum resale fee or a specific league placement of the buying club. These variations allow clubs to tailor the clause to the expected trajectory of the player’s career.

As the competition grew, clubs also started to use sell‑on clauses as a way to balance budgets. A club that sells a player for a modest fee can still benefit if the player becomes a star at another club. This mechanism aligns the interests of both clubs and encourages a more collaborative transfer market.

Edge cases and practical concerns

Certain situations can complicate the straightforward application of sell‑on clauses:

  1. Loan deals with an option to buy - When a player is loaned with a future purchase option, the sell‑on clause usually applies only if the purchase option is exercised. If the club chooses to keep the player or the loan ends without a sale, the clause is not triggered.

  2. Contract termination by mutual consent - If a player leaves a club by mutual termination and then signs for a new club, the original club may still claim a sell‑on fee if the new contract contains a clause referencing the former club.

  3. Transfer fee settlements - In cases where the transfer fee is paid in installments, the sell‑on clause is applied to the total amount received, not to each installment separately.

  4. Disputed ownership - Should a player’s registration rights be shared between clubs (e.g., a joint‑ownership arrangement), the sell‑on clause may need to be negotiated between all parties involved.

Because these scenarios can be complex, clubs often involve legal counsel to ensure the clause is enforceable and that all parties understand the obligations.

Practical examples from the Premier League

Arsenal used a sell‑on clause when they sold a young midfielder to a club in the Championship. The clause ensured that Arsenal received a portion of the resale fee if the player moved to a Premier League club later on. Liverpool also employed a sell‑on clause when they transferred a defender to a Serie A club, securing future income should the player return to the Premier League.

These examples illustrate how sell‑on clauses can be a practical tool for clubs with limited budgets. By incorporating a clause, a club can still benefit from a player’s development even after the initial transfer.

How clubs negotiate the percentage

Negotiating the percentage is part of the transfer dialogue. The selling club will propose a percentage that reflects the player’s potential, the buying club’s willingness to pay, and the overall financial context of the league. Clubs with tight budgets may ask for a higher percentage to offset a lower upfront fee, while clubs with deep pockets might accept a lower percentage in exchange for a larger initial payment.

The percentage is usually capped by the players’ agents and the buying club’s assessment of the player’s future value. In practice, percentages range from 10 % to 30 % in the Premier League, though the exact figure depends on the negotiation.
