Wales captain Sam Warburton was shown a red card for a dangerous tackle on France wing Vincent Clerc after just 18 minutes by referee Alain Rolland, this incident dominating the headlines.
But with a third World Cup final appearance safely in hand, Yachvili insists that no matter what route they took getting there, the class of 2011 have a chance to make themselves heroes back home.
"We know Wales maybe deserved to win because they had the injury [to prop Adam Jones] and a red card," he said.
"We didn't play our best rugby but we won and we are very happy.
"We started this competition very badly but we are proud because of the team spirit in the French team.
"In 1987 France were in the final and those players for us are legends, but now it's us."
