Just pick a Big 6 English Prem team (Manchester United, Manchester City, Tottenham Hotspur (lol i wouldn't), Arsenal (lol x 2), Liverpool, or Chelsea), after watching a few of their matches when the season restarts in August (particularly if they play each other, you'll get their individualistic club vibe that might resonate with you). Most are big London clubs, which, if you end up falling in love with them is a great advantage to eventually go see a live match. Man City is absolutely dominant and they just debatably bought the best young player in the world over the summer. They will be a force. Chelsea has the top American player (for now), though the EPL is now being populated by more and more young americans (you are allowed to have a second team to root for, this isn't like the NFL or someshit - pick Leeds, they have an American manager who saved the club from relegation and then bought perhaps our second or third most exciting young American player over the summer). Everyone hates Man U and loves to watch them fail, so probably don't pick them. In theory, they are the Texas Longhorns of the EPL that brings about so much unfounded anger in even the most casual fans, but in reality the 'Horns are Arsenal who are still considered big 6, have loads of talent and a passionate fan base, but are constantly underachieving.
I wouldn't recommend picking a bottom of the table team hoping to watch them advance up the table over the years and eventually win a spot playing in the champions league (a secondary competition that puts the top of the table teams from all the big Euro leagues in a concurrent season-long tournament to establish the Kings of European football). I did pick Newcastle in 1995 when they were massive, but have fallen off hard since. They just got bought by billionaires from Saudi, so they might eventually buy their way to the top like Man City did, but it takes a while. And also, there is a major moral conflict with your favorite club finding success this way (esp through oil/saudi/russian money).
Anyway, just pick Liverpool and enjoy the run.
What did I forget?
