Homare Sawa just couldn't take it anymore.

The former FIFA Women's World Player of the Year tore into Nadeshiko Japan on Thursday, questioning the heart of some of the players after a disastrous start to the Rio de Janeiro Olympics qualifying campaign.

The morning after Japan on Wednesday allowed archrival South Korea a 1-1 draw at the death, two days following a 3-1 defeat to Australia, Sawa said she has been unconvinced by the performances from her old team and wonders how many of the players truly want to play in Rio.
