Speaking on ServusTV, Freund said: "He's extremely ambitious, but so are the players. They want to win games, they want to win titles, and he knows how they feel in different situations and how to approach them. He simply has a really, really good relationship with the guys and lets them play attractive football.
"The foundation of everything is that they work hard, but also that they have fun. I think there's never been so much running or sprinting at Bayern Munich. But the boys don't mind because they have fun together.
"In the end, we found the perfect coach, who will hopefully stay at Bayern Munich for a very long time."
