Dominic Thiem has separated from his coach Nicolas Massu. The Lower Austrian announced on Instagram on Saturday that the two had decided “that we will go different ways starting next week”. The Chilean Massu, Olympic tennis champion in Athens in 2004, had been touring coach Thiem since the first half of 2019. At that time, the cooperation between Thiem and his long-time coach Günter Bresnik came to an end.
