In the space of a few weeks this summer, Manchester United agreed a £35m fee for Brazilian midfielder Ederson, then watched the deal unravel after a medical revealed an issue. The club moved on to sign Andrey Santos from Chelsea for £50m, but the saga highlights just how fragile football transfers can be. At any moment, a medical, a late World Cup call-up, or a rival club's offer can change everything.
A football transfer is the movement of a player from one club to another, usually involving a fee paid by the buying club to the selling club. The process typically begins when a club identifies a target and makes an inquiry. If the selling club is open to a deal, negotiations over the fee, payment structure, and add-ons follow. Once a fee is agreed, the player must agree personal terms – salary, contract length, bonuses – and pass a medical examination. Only then can the transfer be officially completed during a designated window, such as the summer window (June to August in England).
“Explains how football transfers work, with examples from Man Utd's summer window.”
Manchester United's summer of 2026 demonstrates how complex these deals can be. They prioritised signing a central midfielder after Casemiro's contract expired and Manuel Ugarte was ruled out with a long-term injury. Their first choice, Elliot Anderson of Nottingham Forest, proved too expensive when the fee spiralled to £116m. They then targeted West Ham's Mateus Fernandes, but Tottenham stepped in with a guaranteed £85m offer, and Fernandes chose them. By then, United had already agreed a £35m deal for Atalanta's Ederson on 2 June, expecting him to have a medical in early July. But Ederson received a late call-up to Brazil's World Cup squad, delaying the medical. After Brazil were eliminated, the medical revealed an issue, though sources at both clubs denied the deal was off as of mid-July. The Mirror reported on 10 July that the move had collapsed.
United then turned to Chelsea's Andrey Santos, agreeing a £50m deal (£48m initial, £2m achievable add-ons, plus a 10% sell-on clause) that progressed quickly over a weekend. Santos was cleared for a medical, and his signing addressed the urgent need for a midfielder – with Kobbie Mainoo still at the World Cup and Mason Mount the only recognised senior midfielder available for pre-season.
Why it matters for UK readers Transfers are a central part of Premier League culture, dominating back-page headlines and fan debates. For supporters, a collapsed deal can feel like a major setback, especially when a club misses out on multiple targets. The examples from Manchester United show how clubs can be left scrambling when deals fall through, sometimes leading to panic buys or starting the season with a thin squad. For the broader football economy, transfers involve huge sums – United paid £50m for Santos – and affect club finances, player wages, and even ticket prices. Understanding the process helps fans make sense of breaking news and why some deals succeed while others fail.
Key questions answered
Q: Why do football transfers collapse? Transfers can fall through for many reasons: a player fails a medical, personal terms cannot be agreed, a club changes its mind, or another club makes a better offer. In Ederson's case, a medical issue was reported, though officials denied the deal was off.
Q: What is a medical in football? A medical is a thorough health check to ensure a player is fit to play and does not have underlying conditions that could affect performance or lead to injury. Clubs often use their own doctors, and any issues discovered can cause a transfer to be renegotiated or cancelled.
Q: What are add-ons and sell-on clauses? Add-ons are additional payments linked to performance, such as appearances or team success. A sell-on clause gives the selling club a percentage of any future transfer fee. United's deal for Santos included £2m in achievable add-ons and a 10% sell-on clause for Chelsea.
What happens next Manchester United are expected to complete the signing of Andrey Santos after his medical. The status of the Ederson deal remains unclear – while some sources say it is off, others deny a decision has been made. United will also aim to bring in other targets before the summer window closes, with veteran goalkeeper Karl Darlow close to joining from Leeds. The club's pre-season begins on 18 July against Wrexham, and manager Michael Carrick will hope to have his squad strengthened by then.
