It's a little wooly because of his original stint with Chelsea, but I'd put De Bruyne in the list too - made a name for himself at Wolfsburg and is now the best player in the PL (in my opinion anyway).Sure.
Leroy Sane
Michael Ballack
Nigel de Jong
Son Heung Min
Mesut Ozil
Have all for the most part been a success story in the Premier League, and I think you can include de Bruyne, he barely had Prem experience.
Regardless of what you think of Ozil now, the guy was a creative machine for Woolwich and was superb during his first years for them. I know Ozil didn't come straight from the Bundesliga, but still.
Sabitzer will be fine. Plenty of players have come from the Bundesliga have succeeded in this league. One of the greatest defenders in the leagues history came from the Bundesliga.
Edit: goddamn it I just spotted that you mentioned him afterwards there. Oh well, not deleting.
