Though the Bundesliga has become a two-horse race between Borussia Dortmund and Bayern Munich in recent seasons, fears that it might suffer the fate of Spain are unfounded, Dortmund boss Hans-Joachim Watzke said.

Champions League semifinalist Dortmund, which will take on Spain's Real Madrid on Wednesday in the first leg, won back-to-back Bundesliga titles in 2011 and 2012 before surrendering the trophy to fellow semifinalist Bayern this season.

"Three years (to dominate in the Bundesliga) is not a lot," Watzke said before the much-awaited encounter with the nine-time European champion.
