And Samoa, of course, have a history of delivering memorable results in the World Cup with Wales stunned in 1991 and 1999.
And similar results can't really be considered upsets as the Samoans have shown themselves more than capable of going toe to toe with the best teams in the world as evidenced by their recent win over Australia.
Their squad is sprinkled with quality and many of them ply their trade, like Eliota in the Aviva Premiership.
Eliota himself is going into the tournament after probably the best season of his club career. He lit up the Gloucester midfield with his powerful running and superb distribution skills and cleaned up at the club's end of season awards dinner.
Everyone at Gloucester Rugby hopes that he shines at Rugby World Cup.
