According to the Telegraph , green cards will be applied in some European tournaments next season, possibly the FA Cup in England, used in parallel with yellow and red cards, which are already familiar to football fans.

A green card is given to a player who has committed a foul that prevents a dangerous attack from the opponent or has behaved inappropriately towards the referee. Unlike a red card, if a player receives a green card, he will have to leave the field for 10 minutes and then return to continue playing.

Green cards accumulate in the same way as yellow cards. A player will be sent off and not allowed to return if he receives two green cards or one yellow and one green card.

The appearance of the green card sparked controversy on social media. Many fans wondered about the line between a red card and a green card because for many years, a situation that prevented an opponent from scoring a goal was equivalent to a direct red card. The player who committed this foul only received a yellow card when the foul was committed in the penalty area, but it was accompanied by a penalty.

"If the green card is applied, Atletico Madrid will only play with 6 men in each match," commented Mesut Ozil, former midfielder of Arsenal, Real Madrid and the German national team.

Previously, fans witnessed the referee giving out white cards in the Portuguese women's tournament. Unlike yellow, red and blue cards, white cards are a move to honor actions that demonstrate the spirit of fair play in the match.
