UEFA President Aleksander Ceferin stated that the decision was made with some reluctance, but is considered an exceptional case and will not set a precedent for future decisions.

The matches in question are a game between Barcelona and Villarreal, which will be played in Miami, Florida, and a match between AC Milan and Como, which will take place in Perth, Australia.

The decision to play these games abroad was made after Spain's La Liga agreed to move the match between Barcelona and Villarreal to Miami, and Italy's Serie A decided to stage the match between AC Milan and Como in Perth to avoid a clash with the Winter Olympics opening ceremony at Milan's San Siro stadium.

However, this decision has been met with protests from European supporters groups, who have expressed concerns that these moves are "absurd, unaffordable, and environmentally irresponsible."

Despite this opposition, UEFA stated that it has reiterated its opposition to domestic league matches being played outside their home country, but found that there is no clear regulatory framework in FIFA's statutes to prevent this from happening.

UEFA has approved the two requests on an exceptional basis, citing a lack of a clear regulatory framework in FIFA's statutes to oppose the moves.

It's worth noting that other sports, such as American football and basketball, have been holding games outside of their home countries for years.

The National Football League (NFL) has been holding games in London since 2007, and has also expanded to Mexico and Germany.

The National Basketball Association (NBA) has been relocating regular-season matches since 1990 to Japan and since 2013 to Europe, with games scheduled in Berlin, London, Manchester, and Paris over the next three seasons.

In rugby union, the French Top 14 club competition took its 2016 final to Barcelona's Camp Nou stadium, and Ireland and New Zealand played an international match in Chicago that same year.

La Liga has been trying to host games in the United States for years, and the Spanish and Italian Super Cups are already held in Saudi Arabia.

Football's governing body, FIFA, has shifted its opposition to relocating matches, and a working group was launched in May to revise their rules.

La Liga and Serie A have thanked UEFA for recognizing the exceptional nature of this initiative, and emphasized that this is only one match out of 380 in the league.

This decision is seen as an opportunity for the teams and Italian football to increase their international visibility and fan base.
