With just half a year to go until the Summer Olympics, Japan head coach Hajime Moriyasu is running out of time and sympathy.

Moriyasu, the first coach to take charge of both the Samurai Blue and Olympic squads since Philippe Troussier in 1999, has come under fire following Japan's disastrous AFC U-23 Championship campaign in Thailand.

Reaction from fans and media has been swift and merciless following defeats against Saudi Arabia and Syria as well as a draw with Qatar. Many have called for the former Sanfrecce Hiroshima manager to be dismissed from one — if not both — of his roles.
