The former Germany international has heavily criticised the 20-year-old's impending summer move from Borussia Dortmund to Bayern Munich, slamming the timing of the announcementBorussia Dortmund star Mario Gotze's move to Bayern Munich.
Bayern Munich confirmed on Tuesday that they had reached an agreement with the attacking midfielder after meeting his €37m buy-out clause. He is now set to join the German champions on July 1.
Matthaus, who played for die Roten for 12 years in two spells between 1984 and 2000, and is Germany's most-capped player, made his feelings on the subject clear, however.
"The fans feel ridiculed," the 52-year-old told Sky Sports News HD, adding that the move was "untrustworthy" and "harmful to all of football."
The former sweeper also argued that the timing of the move was "unfair" and "just amazing".
Gotze is now set to become the most expensive German player ever, having won two Bundesliga titles and one DFB-Pokal in his time with die Borussen.
