"In other countries they treat idols differently and I am an idol in Germany," said the former Germany captain, who has coached clubs abroad but never in his homeland.
"This may sound a little cocky but after Franz Beckenbauer I am the second most famous German soccer personality around the world. Germany should be ashamed of the way it treats such an idol," Matthaus told Frankfurter Allgemeine Zeitung on Sunday.
He has coached clubs in Austria, Serbia and Israel as well as the Hungarian national team and had a brief spell in South America with Brazil's Atletico Paranaense in 2006.
"These two things of which I am accused of by clubs have no basis. I am neither Bayern Munich nor am I Bild newspaper. Neither of the two. And these two are my main problems in Germany.
"I hope a German club will just trust me. And only then can you make a judgement: he is good or he is bad," he said.
