West Ham were required to submit their squad to UEFA for the Europa League competition yesterday (4 September 2023 (12.00am CET) for all further matches from the first match in the group stage up to and including the final.

As of the knockout round play-offs, West Ham may register a maximum of three new eligible players for the remaining matches in the current competition. Such registration must be completed by 2 February 2024 (12.00am CET) at the latest.This deadline cannot be extended.

No club may have more than 25 players on List A during the season. As a minimum, eight places are reserved exclusively for “locally trained players” and no club may have more than four “association-trained players” listed in these eight places on List A.

List A must specify the players who qualify as being “locally trained”, as well as whether they are “club-trained” or “association-trained”. A “locally trained player” is either a “club-trained player” or an “association-trained player”. A “club-trained player” is a player who, between the age of 15 (or the start of the season during which he turns 15) and 21 (or the end of the season during which he turns 21), and irrespective of his nationality and age, has been registered with his current club for a period, continuous or not, of three entire seasons (i.e. a period starting with the first official match of the relevant national championship and ending with the last official match of that relevant national championship) or of 36 months. In the context of this paragraph, the season immediately preceding a player’s 15th birthday may be counted if his birthday is after the last match of the relevant national championship but before or on 30 June (winter championships) or 31 December (summer championships), and the season immediately following his 21st birthday may be counted if his birthday is on or after 1 July (winter championships) or 1 January (summer championships) but before the first match of the relevant national championship.

An “association-trained player” is a player who, between the age of 15 (or the start of the season during which the player turns 15) and 21 (or the end of the season during which the player turns 21), and irrespective of his nationality and age, has been registered with a club or with other clubs affiliated to the same association as that of his current club for a period, continuous or not, of three entire seasons (i.e. a period starting with the first official match of the relevant national championship and ending with the last official match of that relevant national championship) or of 36 months. In the context of this paragraph, the season immediately preceding a player’s 15th birthday may be counted if his birthday is after the last match of the relevant national championship but before or on 30 June (winter championships) or 31 December (summer championships), and the season immediately following his 21st birthday may be counted if his birthday is on or after 1 July (winter championships) or 1 January (summer championships) but before the first match of the relevant national championship. If a club has fewer than eight locally trained players in its squad, then the maximum number of players on List A is reduced accordingly.
