BBC Sport answered reader questions on Premier League transfer rules, explaining why some clubs choose not to disclose transfer fees and how "homegrown" player status is determined. Undisclosed fees allow clubs to avoid revealing how much of their transfer budget has been spent or how much money a selling club has available to reinvest, though the practice is often largely symbolic since details usually emerge via agents or other sources anyway; the situation becomes even more pointless when a foreign club involved in the deal is stock-market listed and must disclose the exact fee regardless.

On homegrown status, the article clarifies that it depends on time spent registered with an English or Welsh club before a player's 21st birthday (three seasons or 36 months), not nationality or birthplace. Examples include Chelsea's Joao Pedro, who qualifies despite being Brazilian-born, and Liverpool's Jeremie Frimpong, who qualifies due to nine years in Manchester City's academy, while Eric Dier did not qualify at Tottenham because he completed his football education in Portugal. The piece also touches on sell-on clauses, noting City are understood to retain a 20% sell-on fee for James Trafford following his move.
