Re: Best European football (soccer for US) leagues?
I think Premier League is by far the most competitive, a team like Arsenal could be a serious contender every year in any other league, yet they have to fight teeth and claws to reach a CL spot. Teams like Arsenal and Tottenham are as good as Dortmund, Napoli, Roma, and all the teams I mentioned are considered contenders for the title in their respective leagues.
A few years ago I'd have said Serie A was a close second, but recently it has become Juve and nothing else. I guess if we take away Juve, it remains competitive, but as it is it's a competition for the second place.
La Liga and Bundesliga aren't competition, it's just Barcelona-Real (with Atletico in between recently) and Bayern, nobody else comes even close to compete.
