The Gladbach manager has been in charge at the club since 2011 and has talked up the quality of the German league ahead of the start of the new Bundesliga campaign.
"In my opinion, the Bundesliga's the most attractive league in the world because we have an average of around 45,000 fans per game," he told the Bundesliga's official website in an interview.
"That's far more than in England or in Spain. The hype in Germany is amazing, and now they've won the World Cup so it's not going to tail off in a rush.
"You've got to work really hard if you want to survive in this league because it's so even."
The new season gets underway next weekend, with Gladbach due to face VfB Stuttgart.
