What looked like a modest exit for Bayer Leverkusen is now turning into a seriously tidy piece of business. Gustavo Puerta is set to move from Racing Santander to Nottingham Forest, and Leverkusen are in line to receive €8.5m from the deal. That is not pocket change. That is the sort of return that makes clubs sit up and remember that smart contract clauses can be worth far more than a player’s short-term role in the team.
The key detail is simple enough. Leverkusen sold Puerta to Racing Santander in 2025 for €1m, but retained a 50 percent share of any future transfer profit after the player had left the BayArena. Now Nottingham Forest are preparing to trigger his €18m release clause, and the numbers do the rest. A player who did not establish himself as an important first-team option in Leverkusen is suddenly generating a major windfall for his former club.
How the money stacks up
This is exactly why future-transfer provisions matter. Puerta joined Bayer from Bogotá FC in January 2023 for approximately €1m, spent the 2024/25 campaign on loan at Hull City, and later moved on again. None of that suggested a headline-making asset was being built at the BayArena. But Leverkusen protected themselves, and that is the part other clubs should study instead of shrugging at the original sale price.
The report says strong performances at the 2026 World Cup helped transform Puerta’s value, and that matters too. Transfer value is rarely just about what a player has done for one club. Sometimes it is about timing, form and the market all exploding at once. In this case, Leverkusen have benefited because they did not simply cash out and walk away. They left themselves attached to the upside.
That is the real lesson here, and it is bigger than one midfielder. A club does not always need to win the immediate transaction if it can structure the long game properly. Leverkusen accepted a modest fee, kept half of the future profit, and now the market is paying them back in full. It is the kind of deal that looks cautious at first and clever later.
Puerta’s path is now clear enough: Racing Santander to Nottingham Forest, then a loan straight to Olympiakos for the 2026/27 season. And while the player himself is the one moving through the chain, the standout winner is Leverkusen, who have turned a low-key exit into an €8.5m return. In a market that too often rewards short-term thinking, that is exactly the sort of business clubs should be trying to copy.
