Romania started their World Cup campaign with a loss against France, and even though Philippe Saint Andre's side put five tries past them, they're not an opposition that should be taken too lightly.  

World Ranking: 17

Key Player: Catalin Fercu. The Saracens player has pace to burn and having scored 28 tries at international level, he knows how to unlock defences and is unlikely to get a case of white line fever if Romania put the pressure on Ireland. Even in his defensive duties, he's also showed that he puts his pace to great use and can read the game very well. 

Head Coach: Lynn Howells

RWC Appearances: 7

Best Result: One Pool win in 1987, 1991, 1999, 2003 and 2007

Did you know?: Romania are only one of eight teams to lose a World Cup match without scoring after they were on the wrong end of a 0-42 scoreline against Scotland back in 2007.
