think about it
the underlying assumption being, that there would be free and easy access to stadia to play in
ie
the Bundesliga could decide to play certain games in England, Spain, France....
for instance, HSV vs SChalke could be played in Amsterdam; Bremen vs Bayern in the Emirates STadium....
whereas the EPL could try to retaliate by having Liverpool vs Chelsea played in Dortmund with Juve vs Milan trying to win fans for Italian football in the Nou Camp
think about it
