Барав линк каде што пишува за правилото дека е дозволено да се регистрира играч во ЛШ кој претходно бил регистриран за друг тим.
Еве како се правилата:
Player Eligibility
...
18.07 As a rule, a player may not play in a UEFA club competition (i.e. UEFA
Champions League and UEFA Europa League, but not UEFA Super Cup) for
more than one club in the course of the same season. Exceptionally,
however, a player who has been fielded in the first, second or third qualifying
round 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, provided that his former club did not qualify for
the group phase of either the UEFA Champions League or the UEFA Europa
League; moreover, as from the start of the round of 16 (round of 32 for UEFA
Europa League), a player can be registered in accordance with paragraphs
18.17 to 18.20 below. For the avoidance of doubt, 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.
Subsequent registration
18.17 For all matches from the start of the round of 16, a club may register a
maximum of three new eligible players for the remaining matches in the
current competition. Such registration must be completed by
1 February 2011 (24.00 CET) at the latest. This deadline cannot be
extended.
18.18 One player from the above quota of three who has played UEFA club
competition matches for another competing club in the current season may
exceptionally be registered, provided that the player has not been fielded:
− in the same competition for another club; or
− for another club that is currently in the same competition.
Furthermore, if the player’s new club is playing in the UEFA Europa League,
his former club must not have played in the UEFA Europa League at any
point in the current season.
18.19 If the registration of such new players causes the authorised number of
players on List A to exceed 25, the club must remove the necessary number
of currently registered players to reduce the squad to 25 players again. The
quota of the “locally trained players” must be respected when registering new
players. Newly registered players must wear set numbers which have not yet
been assigned.
18.20 If a club cannot count on the services of at least two goalkeepers registered
on List A because of long-term injury or illness, the club concerned may
temporarily replace the goalkeeper concerned and register a new goalkeeper
at any time during the season and complete the official registration list A with
a goalkeeper fit to be fielded. An injury or illness is considered long-term if it
lasts at least 30 days as of the day the injury or illness occurred. In case the
recovery of the goalkeeper occurs before this 30 day period, the player must
remain out of the players List A until the end of such period. If the replaced
goalkeeper was registered as a locally trained player, the new goalkeeper
does not need to be a locally trained player. The club must provide UEFA
with the necessary medical evidence in one of UEFA's official languages.
UEFA may require further medical examination of the goalkeeper by an 28
expert appointed by UEFA at the cost of the club. Once the injured or ill
goalkeeper is fit to be fielded again he can resume his position in place of his
nominated substitute. The change must be announced to the UEFA
administration 24 hours before the next match in which the goalkeeper is due
to play.
