Tonga head coach Mana Otai has admitted that "technical errors" played a part in his side's 17-10 loss at the hands of Georgia this afternoon.

A number of mistakes and penalties contributed to the Pacific Islanders' surprise defeat at Kingsholm, with Tonga failing to make the most of sustained pressure inside the Georgian 22 late on.

Otai does not believe that ill-discipline was to blame, but acknowledged that his side did not help themselves with a series of mistakes.

"I think it's not quite ill-discipline, more like technical errors. It was nothing about foul play as such, it was more technical issues that we addressed at half time," he told Sports Mole.

"Maybe coming off our feet at times when we were cleaning up. There was one that was on the neck where the idea was to take the opposition away, but the defender was not the right way of doing it. And of course in the scrums we got penalised a few times as well."

Tonga take on Namibia on September 29 in their next Pool C match, before facing Argentina and New Zealand in the space of five days.
