Roma are expected to receive about €6m from the Riccardo Calafiori transfer dispute after the Court of Arbitration for Sport heard the case between the Italian club and Basel. The money would close out a fight over how sell-on clauses should work when a selling club makes money twice from the same player.
That question has followed Calafiori for years. Roma first let him go to Basel in August 2022 for €2.5m and kept a 40% sell-on clause, then Basel sold him on to Bologna a year and a day later for €4m, with its own 50% clause attached. Basel later banked a much larger windfall when Arsenal paid €40m plus €5m in add-ons for the defender, and Roma argued that part of that extra profit should flow back through its original agreement.
Calafiori's rise has made the numbers look small by comparison. The 16-year-old who once suffered a serious knee injury at Roma later made 18 first-team appearances for the club before leaving permanently after the second half of the previous season on loan at Genoa. Bologna then turned him into a Serie A Team of the Year centre-back, and the line from that breakthrough to Arsenal's bid has made the old contract wording suddenly valuable.
Basel has pushed back on that reading. Its case was that Roma's clause should only have applied to Calafiori's direct move away from the Swiss club, not to any later resale gain Basel made on the way to Bologna and beyond. Roma's argument cuts the other way: once Basel earned extra money from the second sale, that money should have been counted under the original deal.
The outcome matters beyond this one transfer. Clubs regularly build sell-on clauses into deals to protect themselves when a player moves on, and the Calafiori case could shape how those clauses are written the next time a club sells a player for a modest fee and then watches his value rise sharply elsewhere. Roma also have a separate reason to care about the timing, with the club locked in a Financial Fair Play settlement agreement with UEFA for the past four years and potentially able to come out of it this summer.
For now, the expected €6m payment looks like the practical end point of a messy paper fight over who gets paid when a player moves twice. What CAS confirms next will matter less for Calafiori himself than for the clubs still trying to decide how much of a future resale they can really protect.
