Form: Thrashed by Japan in the build up to the World Cup, it could be argued that just in qualifying for the global showpiece, Uruguay have succeeded. Toppling Russia over two legs earned the South Americans their place at the tournament, but a long four weeks awaits with four heavy defeats likely.
Captain: Santiago Vilaseca. Uruguay were dealt a blow when experienced back row Rodrigo Capo Ortega, who also played in the 2003 World Cup, unexpectedly announced his international retirement. Hard-working flanker Vilaseca has stepped into the breach.
Star player: Felipe Berchesi. The fly-half is a reliable kicker out of hand and from the tee and is the pivot for Uruguay's attack. A strong game-manager and will need to be when he faces Australia, England, Wales and Fiji.
World Cup history: England 2015 will be Uruguay's third World Cup and the South Americans be hoping to improve on a record of two wins from seven matches. In 2003 England scored 111 points against them.
