These new cards will lead to a ten-minute expulsion for players committing tactical fouls or protesting referee decisions. This new protocol will limit blue cards to fouls that disrupt "promising attacks" or player protests. Additionally, a player will be sent off from the match if they receive two blue cards, or a combination of one blue and one yellow (and vice versa).

"I don't know if we are ready for this. We already have a lot going on with decisions, with technology... I don't know if we are ready for that yet. I hope they test it thoroughly before introducing it at this level," Arteta said in a press conference on Friday.

Arteta's sentiment echoes that of Chelsea's Mauricio Pochettino, who noted that it is "not a good idea," and Liverpool's Jürgen Klopp, who stated that it is not a "fantastic idea" and that the International Board (IFAB) rarely has a good idea.

Pep Guardiola has remained neutral, stating that he won't give his opinion until it is official.

This measure will mark the first introduction of a new disciplinary card since the arrival of yellow and red cards in the 1970 World Cup.
