<Li> The team that scores the most successful kicks at the end of the shoot - out will be the winner of the match . </Li> <Li> Only players who were on the pitch at the end of play or temporarily absent (injured, adjusting equipment etc .) will be allowed to participate in the shoot - out . If at the end of the match and before or during the kicks one side has more players on the pitch than the other, whether as a result of injury or red cards, then the side with more players must reduce its numbers to match the opponents; this is known as' reduce to equate' . For example, if Team A has 11 players but Team B only has 10, then Team A will choose one player who will not take part . Players excluded this way normally take no further part in the procedure, except that they can be used to replace an injured goalkeeper . The rule was introduced by the International Football Association Board in February 2000 because previously an eleventh kick would be taken by the eleventh (i.e. weakest) player of a full - strength team and the first (i.e. strongest) player of a sub-strength team . A rule change in 2016 eliminated the possibility of a team gaining such an advantage if a player is injured or sent off during the shoot - out . </Li> <Li> A team may replace a goalkeeper who becomes injured during the shoot - out with a substitute (provided the team has not already used the maximum number of substitutes allowed by the competition) or by a player previously excluded under the' reduce to equate' provision . </Li> <Li> If a goalkeeper is sent off during the shoot - out, another player who finished the game must act as goalkeeper . </Li>
