VIDEO: Furious Eddie loses his cool

Wallabies head coach Eddie Jones could not contain his frustration as his side suffered a last-minute 31-34 defeat to Argentina in Sydney on Saturday.

At the back of a demoralizing 12-43 defeat to South Africa in the Rugby Championship opener last week, Jones was fuming as Argentina snatched a win at the end of the action-packed Round Two on Saturday.

Waratahs wing Mark Nawaqanitawase looked to have saved the Wallabies' blushes with a rousing 95-metre intercept try, handing his side a 31-27 lead with five minutes remaining in Sydney.

However, a 79th-minute try to Juan Martin Gonzalez denied Wallabies the win and handed Jones his second consecutive loss since returning as Wallabies coach.

To add salt to the injury,  it also marks the first time in Australian rugby history that the Wallabies have lost back-to-back Tests against the Los Pumas.

The loss has placed huge pressure on Jones, who was seen losing his composure in the coaches box.

In a video, the 62-year-old enraged by the turn of events, could be seen ripping off his headset and slamming it onto the desk in front of him.

The Wallabies next meet a dangerous New Zealand – who toppled the Springboks 35-20 in Auckland on Saturday – at the Melbourne Cricket Ground before a return leg in Dunedin ahead of the World Cup in France.
