I think Football in general has declined a lot.
If you watch games from the 80’s and 90’s, you’ll see all kinds of excellent technique, plays, and skill.
These days, it’s all about preventing the other team from scoring. This is how teams like Andorra only lose 0-1 to the Netherlands.
This has been the worst Euro tournament that I can recall.
It's also because it seems anytime a defender so much as breathes on an attacking player, it's called as a foul. If you watch games from the 70s, stuff that would be a straight Red Card now, wouldn't even be called as fouls.
