India's two-time Olympic medal-winning javelin thrower Neeraj Chopra and his long-time German coach Klaus Bartonietz have parted ways. The 75-year-old German has decided to return home to spend time with his family. "Bartonietz wasn't willing to continue after 2021 but we requested him and he agreed..but this time he's going back,” Athletics Federation of India chief coach Radhakrishnan Nair said.
