They might be in Europe, but we are a decent club in the premier league man!
What you might not notice if you don't live in Germany is that Bundesliga is huge there. They have same coverage as the Premier League in England if not even more, and the average attendance is a bit above the one in Premier League and has been for a couple of years. There is a reason why you don't see that many transfers from Bundesliga to for example Premier League and that top players there say they only want to move abroad for Champions League football.
So I guess players who lives and plays in Germany doesn't see Premier League (except for the top 4 teams) as any greater then Bundesliga.
