Form: The US Eagles enter the tournament after two confidence-building wins over neighbours Canada. That followed a victory over pool rivals Japan, a result which was sandwiched by losses to Samoa and Tonga. There are talented individuals in the squad but that might not be enough to see them seriously challenge the likes of South Africa and Scotland.
Captain: Chris Wyles. The impressive wing or full-back is a mainstay for Saracens and will be playing in his third World Cup, after featuring in the 2007 and 2011 tournaments.
Star player: Samu Manoa. The No.8 is one of the best in European club rugby, so good that Toulon have handed him a four-year contract to prise him from Northampton.
World Cup history: The USA have won three games in 21 attempts in tournament history, the most recent coming in 2011 against Russia. The Eagles also won twice against pool opponents Japan, in 1987 and 2003 and they are still to advance from the group stages.
