German fans fear rise of 'plastic clubs'

The promotion of RB Leipzig to the Bundesliga has caused resentment among hardcore fans of traditional teams, sparking fears that 'plastic clubs' could ruin the traditional culture in Germany's top flight.

RB Leipzig is backed by Austrian energy drink giant Red Bull, which took over a soccer license and founded the club in 2009.

The team was renamed RasenBallsport Leipzig, specifically to get around the German league rule forbidding teams from carrying a sponsor's name.
