Homegrown rule forces Manchester United to prioritise domestic signings this summer

Manchester United face a structural constraint in their summer transfer window after the Premier League’s homegrown quota rule left them with precisely eight eligible players — and one of those, Toby Collyer, is expected to leave the club.

Premier League regulations require any club submitting a full 25-man squad to include at least eight homegrown players, defined as anyone trained by a club in the United Kingdom for a minimum of three years before their 21st birthday. Under-21 players sit outside the registered list entirely and can still feature in matches, but they do not count towards the quota.

United’s current homegrown contingent consists of Tom Heaton, Dermot Mee, Harry Maguire, Luke Shaw, Kobbie Mainoo, Collyer, Mason Mount, and Amad. That is exactly the minimum required — leaving no margin for error.

Collyer, 22, spent last season on loan in the Championship and is keen to secure regular first-team football. All options for a departure are said to be on the table this summer, and his exit is considered likely. Should he leave, United would drop below the threshold and be unable to register a full 25-man list without adding a qualifying replacement.

That dynamic helps explain the club’s reported interest in goalkeepers Karl Darlow and Sam Johnstone, both of whom would satisfy the homegrown requirement. Radek Vitek also qualifies but is himself expected to depart.

The situation is further complicated by the Champions League’s own registration rules. UEFA requires clubs to name eight homegrown players on their European squad list, but splits the definition: four must be trained specifically by the club for three years between the ages of 15 and 21, while the remaining four can have been developed by any academy within the same national association.

Patrick Dorgu and Kobbie Mainoo were both classified as Under-21 players last season but have since turned 21, meaning they now occupy spots on the senior registered list. Ayden Heaven and Leny Yoro remain below 21 and do not need to be included.

United are expected to play 60 or more games across all competitions in 2026/27, making a full 25-man squad a practical necessity rather than a luxury — and the homegrown arithmetic a genuine factor in how the club approaches the market this summer.
