I worked in an insurance company and even if all have learned English as second language - and about all of them had the German Abitur (the permission to go to German university - we have a school system that divides into 3 sectors after elementary school) where they learned atleast 2 languages - whenever we got an English caller on the other side of the phone they did not try to answer but connected the caller to me. A lot can read English very well but are unsure when it is about talking, are afraid to speak and make mistakes. There is really a big difference between being immersed into the language and theoretically to just being able to understand it.
The northern European countries do not even translate English films into their own language but show them with undertitles. I think it is the same with the Netherlands. Austria speaks German - and with so many German speaking people about every film is translated.
I was unsure on which level Sabitzer is in his English. What I could find out is that he does not have a higher education but just went to the "necessary" schools before starting his career. But he for sure had some years of English in school, needed English before in international dressing rooms like the one in Leipzig and is travelling around a lot like most professionals. So English for sure is not a problem for him.
That is true, though you see more dubs recently than you used to when I was a kid. Then again, with netflix and youtube and stuff there’s more places to learn English than playing Pokémon (not translated to Dutch, like many games).
But still, even here there are people who suck at English. In smaller towns it’s not really necessary and in the east of the country you’re generally better off learning some German.
From the places I’ve been in Germany and Austria, the big city factor seems even more prominent in your chance of finding some people to speak to in English rather than German.
People I work with in France, mostly speak English (though troublesome) for teams meetings, and honestly in reverse it often isn’t of much higher quality than just getting by, for a lot of people.
I guess what I’m trying to say is that I agree that Swedes and Danes and big city-Dutchies seem to be more the exception than the rule concerning their knowledge of the English language, simply because English isn’t that important if you’re not in an international job or surrounded by expats.
And thankfully ETH is from Twente so his German is probably better than his English is, so I assume Sabitzer gets time to settle in without having to rely on only hand gestures.
