Ex-Germany midfielder Didi Hamann termed Germany defender Antonio Rüdiger's decision to mock Japanese player Takuma Asano's running style during their recent 2022 FIFA World Cup match as "very unprofessional". "You don't belittle the opposition like that...He was having a laugh, there's only one team having a laugh now...I've got no explanation...for it," said Hamann. Japan recorded a 2-1 win.
