'According to UEFA regulations. See in particular at the bottom Rule 18.18. Suarez can not play.
Conditions for registration: List A
18.08 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 on
these eight places on List A. List A must specify at least eight players who
qualify as being “locally trained”, as well as whether they are “club-trained” or
“association-trained”. The possible combinations that enable clubs to comply
with the List A requirements are set out in Annex VIII.
18.09 A “locally trained player” is either a “club-trained player” or an “associationtrained
player”.
18.10 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.
18.11 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 national association as that of his current club for a
period, continuous or not, of three entire seasons or of 36 months.
18.12 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.
18.13 List A has to be submitted by the following fixed deadlines:
a) 21 June 2010 (24.00 CET) for all matches in the first qualifying round;
b) 9 July 2010(24.00 CET) for all matches in the second qualifying round;
c) 23 July 2010 (24.00 CET) for all matches in the third qualifying round;
d) 9 August 2010 (24.00 CET) for all matches in the play-off round;
e) 1st September 2010 (24.00 CET) for all further matches from the first
match in the group stage up to and including the final.
18.14 For the three qualifying rounds and the play-offs, after the above-mentioned
qualifying dates, one player on List A may be changed until 24.00 CET on
the day before the relevant first-leg match, provided that the club’s national
association confirms in writing that the new player is eligible to play at
domestic level at this time.
Conditions for registration: List B
18.15 Each club is entitled to register an unlimited number of players on List B
during the season. The list must be submitted by no later than 24.00 CET on
the day before the match in question.
18.16 A player may be registered on List B if he is born on or after 1 January 1989
and has been eligible to play for the club concerned for any uninterrupted
period of two years since his 15th birthday by the time he is registered with
UEFA. Players aged 16 may be registered on List B if they have been
registered with the participating club for the previous two years without
interruption.
Subsequent registration
18.17 For all matches from the start of the round of 32, 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.'
i think hes wrong because it says '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'.
suarezs' new club lfc are in the EL and his previous ARE but they havent played in the EL at anyu point in the current season so therefore he can play for us LFC in the EL

unless they make up some ore [oops].
