Anyone who thinks La Liga is a better league actually watch it?
There is fantastically entertaining football up and down the league but 2/3 of the team are absolutely dire quality-wise. Especially the defending which is embarrassing and would look in place in League One.
Barca and Real are better than our entire league, I think they are #1 and #2 in Europe with United being #3. Valencia and Villarreal come next and are decent sides but not as good as probably the top 6 English clubs. Sevilla, Bilbao, and the current version of Atletico Madrid (deteriorated and gonna be even worse if De Gea and Kun leave) would all probably be able to fight for top half spots in England but wouldn't be guaranteed.
Teams like Almeria, Hercules, Mallorca, and Getafe... well, what can you say, I think sides like Charlton, Hull, and Ipswich could beat them 7 times out of 10.
