Reigning HSBC World Rugby Sevens Series champions and Olympic gold medallists Fiji were one of four teams to maintain a 100 per cent win record on day one of the Dubai Sevens and march into the Cup quarter-finals. 

The Pacific islanders took a major step towards retaining their Dubai Sevens title with three wins in Pool A over Wales, Argentina and Canada, providing some thrilling rugby at the opening round of the world series. 

They will face France in the final eight and will be joined by three other unbeaten sides from day one as South Africa, England and Australia all shone bright in the Dubai sun. 

"We're happy with how we performed but we knew it was going to be tough," said Fiji captain Osea Kolinisau. "We got three wins in the bag, and a win is a win. We learned a lot from the first three games.

"Against Argentina we knew they were going to throw the kitchen sink at us because they had lost to Wales. I am proud of the way the boys were resilient. We were down twice and had two yellow cards, but the boys came back so it's testament to them."
