France's match-winner Paul Pogba hailed his late header as one of the best moments of his life as Les Bleus swept into the World Cup quarter-finals after beating Nigeria 2-0 in Brasilia.
Pogba struck the crucial blow in the 79th minute before Joseph Yobo's injury-time own goal put the gloss on the result for Didier Deschamps' side.
Pogba said: "I have no words to describe this feeling. The whole country is behind us and scoring that goal really liberated us. I am so happy for the team and all of France.
"To score a goal for your country, especially in such an important game as this, to get into the last eight of the World Cup is one of the best moments of my life."
Deschamps said he was "very proud" of his side but admitted that France had suffered from the tension.
He said: "We're in the quarter-finals now and we will do everything we can to go one step further."
Nigeria coach Stephen Keshi said he did not know what would happen about his future, and criticised USA referee Mark Geiger.
Keshi said: "I thought the referee made a lot of mistakes and was very lenient to the French players. There was a very bad tackle on Ogenyi Onazi and he is probably out for weeks."
