Materazzi was player-coach of Chennaiyin in the HeroISL last year.
The 41-year-old says he would be happy to take charge of a team in the Bundesliga one day.
"In Germany, they've been planning and doing great things since the World Cup in 2006, as evidenced by the signing of [Pep] Guardiola for Bayern Munich and the World Cup victory in Brazil.
"Years ago my agent told me that I had a request from Kaiserslautern. Back then, however, I didn't want to leave Italy. Players who did that stopped being considered for the Italian national team and I didn't want that.
"Besides, I had a responsibility towards my family. My father was a Coach, and as a child I continuously had to change cities. This isn't exactly ideal for a family, though I can't deny the Bundesliga attracted me.
"After Berlin I had a lot of opportunities to join other clubs and make better money, but I stuck with Inter and we won it all. The climax was the Champions League Final against Bayern Munich in 2010.
"What I want above all else is to win, having fun or making money are not my priorities in football."
