Trinh-Duc's drop goal helped France beat England 19–12 at Eden Park in quarter final in 2011 Rugby World Cup. He came on as a substitute for the injured Morgan Parra in the 23rd minute of the final against New Zealand. He set in motion the move that led to Thierry Dusautoir's try in the 47th minute and converted the try to make the score 8–7. With 15 minutes remaining and the score still at 8–7, France were awarded a penalty to put them in front for the first time, but Trinh-Duc's 48m penalty attempt was wide off the mark and the All Blacks went on to win the final.
