¹ Premier League clubs have to register a first-team squad of no more than 25 players, of which a maximum of 17 can be non-homegrown. In addition, all clubs are allowed to use as many U21 players as they wish during the season.

² According to Premier League rules, a homegrown player is someone who has been registered to an English (or Welsh) club for a combined period of three seasons (36 months) prior to his 21st birthday (or the end of the season during which he turns 21).

³ A player is considered U21 if he is under the age of 21 on January 1st in the year in which the season commences. For the 2018-2019 season this means any player born on or after January 1st, 1997. For example: if a player turned 21 on 31 December 2023, he would not be considered U21 for the 2018-2019 season. However, if he turned 21 on 1 January 2024, he'd be considered U21 and would not have to be named in the 25-man squad for the 2018-2019 season.
