For one, it’s the most popular one
For two, it has the highest stadium attendance and TV viewership in the higher leagues. You’ll never feel alone.
For three, although Barcelona edge out as the best, the balance of power among teams, especially within the English Premier League, is not lopsided which makes for great unpredictability and entertainment.
The immense hype and stadium atmosphere leading to and during the matches . I’m watching the UCL final atm which is the most viewed annual sports event on the planet and I can assure you this is one of the tensest moments of my life like every other year.
