As a German I'm fine with Alemaan (note that the German name for Germany is nothing like Germany either).
But it's worth noting that in German "Alman" has become the equivalent of "gammon" in the UK, especially among immigrants and in youth culture. I.e. a derogatory slur for a specific type of native-born person (usually men) holding naïvely reactionary views. Not necessarily intentionally racist but always ignorant.
