Why Do Transfers Collapse at the Last Minute? 6 Reasons
Medicals, agent fees and buy-back clauses: the six most common reasons a done deal falls apart before it's signed.

Transfer deadline day is full of deals that look certain right up until they fail to go through. A move can be "here we go" one hour and dead the next, and it usually comes down to one of the same six reasons.
1. Failed medicals
Clubs run a full medical before confirming any signing, and a scan can reveal an old injury or a fresh issue that wasn't picked up before. Since medicals are often left until personal terms are close to agreed, a bad result late in the process can sink a deal with almost no time to react.
2. Player-side disagreements over personal terms
Two clubs agreeing a fee is only half the deal. The player still has to agree wages, bonuses, image rights and contract length with the buying club, and talks over those details can drag on and collapse even after a fee is settled.
3. Financial details between clubs
Add-ons, sell-on clauses and payment schedules can hold up a transfer just as easily as the headline fee. Clubs will often walk away over how a fee is structured, even if the total number was never really in dispute.
4. Missed regulatory or administrative deadlines
Transfers need paperwork filed correctly and on time, often across two or three national federations plus FIFA's international clearance system. A single missing document or a system outage near the deadline can be enough to void an otherwise-completed deal.
5. A third club hijacking the deal
Nothing is final until contracts are signed, which leaves room for a rival club to swoop in with a better offer for the player or a higher fee for the selling club. These hijacks are most common right at the deadline, when panic buying is at its peak.
6. The selling club changing its mind
Sometimes the fee and terms are all agreed, but the selling club gets cold feet, often because they can't find a replacement in time or a director overrules the deal at the last minute.
Frequently Asked Questions
Can a transfer still go through after the deadline passes?
Only in rare cases. Some leagues allow a deal to be completed if the paperwork was submitted before the deadline but processed slightly late, but as a rule, once the window closes the deal is off until the next one opens.
Why do failed medicals happen so often at the last minute?
Medicals are usually scheduled right before the deal is announced, since clubs don't want to run one until personal terms are agreed. That means a physical issue often only surfaces in the final hours of a deal, when there's little time left to renegotiate.
What is a transfer hijack?
It's when a third club swoops in with a better offer while two clubs are still finalising a deal. Because nothing is binding until contracts are signed, a rival can gazump an 'agreed' transfer right up until the last moment.
