UEFA have made changes to the rules on yellow cards for their club competitions to make it harder for players to be suspended for the Champions League and Europa League finals.
If a player reaches three bookings over the course of the tournament, they will gain a ban, but the European governing body has decided that yellow cards accrued will be wiped out after the quarter-final stage.
The change means a player could not miss the final unless they received three yellows over the two semi-final legs, but as that would result in a sending off in one of the games, a suspension would be given anyway.
Real Madrid's Xabi Alonso missed last season's Champions League final after picking up a third caution in the semi-final against Bayern Munich.
Spanish midfielder Alonso is among other players who have missed the final after picking up a booking in the last four - Roy Keane and Paul Scholes suffered a similar fate in 1999.
Uefa acted on the recommendation of a panel set up by its Competitions Committee.
A statement read: "The Emergency Panel decided that, as of this season, all yellow cards from the beginning of the group stage will expire on completion of the quarter-finals. Bookings will therefore not be carried forward to the semi-finals."
