Article 43 Player eligibility - Champions League

Regulations of the UEFA Champions League

Competition Regulations
24 September 2020

In order to be eligible to participate in the competition, players must be registered with UEFA within the requested deadlines to play for a club and fulfil all the conditions set out in the following provisions. Only players that are duly registered with UEFA by means of list A or B can validly serve pending suspensions.


Each player must be duly registered with their national association as playing for the club concerned in accordance with the association’s own rules and those of FIFA, notably the FIFA Regulations on the Status and Transfer of Players.


Each player taking part in the competition must be in possession of a player’s registration licence issued by his association or a valid passport or identity card, each containing his photograph and giving full particulars of his date of birth (day, month, year). The referee or the UEFA match delegate may ask to see the passports/identity cards of the players listed on the match sheet.


All players must undergo a medical examination to the extent provided for by the UEFA Medical Regulations.


The club bears the legal consequences for fielding a player who is not named on list A or B, or who is otherwise not eligible to play.


As a rule, a player may not play in the UEFA Champions League and/or UEFA Europa League for more than one club in the course of the same season. Exceptionally, however, a player who has been fielded in the first, second, third qualifying round or the play-offs of the UEFA Champions League or UEFA Europa League is entitled to play in the UEFA Champions League or UEFA Europa League for another club as from the group stage. Moreover, as from the start of the round of 16, a player can be registered in accordance with Paragraph 45.01 to Paragraph 45.03. A substitute player who has not been fielded is entitled to play for another club competing in the UEFA Champions League or UEFA Europa League in the course of the same season, provided that he is registered with the UEFA administration in accordance with the present regulations.


The UEFA administration decides on questions of player eligibility. Challenged decisions are dealt with by the UEFA Control, Ethics and Disciplinary Body.
