Summarizing UCL winners and context

I’m looking at when Porto won the UCL in 2004 and defining the top five leagues as England, Spain, Italy, Germany, and France. Since 2004, teams from these leagues winning include Liverpool, Barcelona, and Real Madrid, among others. It’s interesting that after 2004, there hasn't been a winner from outside these leagues. Notably, some teams like AS Monaco and Borussia Dortmund have reached the finals while being in a top league. This context really highlights the strength of the top leagues!Analyzing UCL finalists and context

Since 2004, there have only been three non-top-5 finalists: 2019 Tottenham and 2005 Liverpool versus Milan were both in top leagues. For semifinalists, Ajax in 2019 and PSV in 2005 are notable, while Porto reached the quarterfinals. Monaco also made it to the semifinals in 2017. There are structural reasons behind these outcomes, such as finances and TV money. I wonder if you'd like me to provide a translation, fact-check, or opinion on this!Exploring UCL Winners and Context

I want to confirm the quote about Porto’s 2004 win. Since then, all UCL winners have come from the top five leagues, and the last non-top-5 winners were Ajax in '95, PSV in '88, and Red Star in '91. It's harder for non-top-5 teams now, due to financial gaps and the Champions League format. I wonder which non-top-5 teams, like Benfica and RB Salzburg, could be dark horses? Would you like a quick fact-check or some context on this?
