The former Bayern Munich midfielder believes that the English top-flight is of a much higher standard than its German counterpart
Michael Ballack sees "a big difference in quality" between the Bundesliga and the Premier League, with Germany's top flight lagging behind.
Concerns have been raised in Germany after Borussia Dortmund and RB Leipzig were eliminated from the Champions League group stage, while Hoffenheim did not even get that far after losing their qualifying play-off against Liverpool.
Bayern Munich are the only Bundesliga side remaining in Europe's premier club competition and Jupp Heynckes' side hold a 19-point lead at the summit of the domestic league, which they are set to win for a sixth season in succession.
