With Bayern Munich and Borussia Dortmund having reached the Champions League semifinals, there are concerns the German league will suffer from what is being dubbed a "Spanish situation" with the pair set to dominate the Bundesliga for years to come.

Bayern hosts Barcelona in Tuesday's semifinal first leg, having cruised to the Bundesliga title with alarming ease and a massive 20-point lead, while second-placed Dortmund, who have won the last two league titles, hosts Real Madrid on Wednesday in the last four.

Bavarian giant Bayern has won 22 of the 50 Bundesliga titles since the competition started, but this season has been extraordinary even by its lofty standards.
