Thanks, ok, so I won't use an -s when talking about a team.
I personally would always say "The Netherlands" or "Holland" followed by the singular. This would not change if I were referring to a team. Would you say: "Germany are a highly skilled team"? I would say: "Germany is a great team" or "The German players are a highly skilled team."
I was born in Germany, so I guess I'm a real German.
However, I dislike the way they play.
It doesn't look interesting to me.
The Germans smash teams that have already given up.
It's as if you keep kicking a guy who's already lying.
I still believe if there hadn't been the lucky goal in the 3rd minute, it could have ended differently.
And many Germans have already a very big mouth, and if Germany actually win[STRIKE]
s[/STRIKE];-) the World Cup, they (the citizen) would all feel like "heroes".
They should come back down...
(Sure it could be the same in other countries, but since I'm not there, I don't care

)
P.S: Does Brazil and Argentina speak the same language?
No, Brazilians speak Portuguese and Argentinians speak Spanish (although with a pronunciation that reminds me of Portuguese.) So...I would prefer to say "Brazilians" rather than "Brazil." If I did use the country names I would say, "Brazil and Argentina use a different language." Only people (e.g., Brazilians) speak, not countries.
Cheers!
