Eta makes history at Union Berlin - what does it mean for football?

Marie-Louise Eta's ascendance to the head coach role at Union Berlin has been chronicled by some as an obvious move. An assistant stepping up to take the reins after previous boss, Steffen Baumgart, suffered the sack. The chain of events makes perfect sense.

Except this is no ordinary takeover. This has significance beyond the realms of Union's Bundesliga survival with five games to play. Beyond the shores of German football entirely, in fact.
