Antoine Griezmann has revealed that a heated dressing-room exchange between the French players inspired their second-half comeback against the Republic of Ireland.
France walked off of the pitch at half-time with boos ringing around the Stade des Lumieres after Robbie Brady had given Ireland an unlikely lead with a second-minute penalty.
Martin O'Neil's men continued to look dangerous despite holding onto a precious advantage with Les Bleus looking more likely to concede than equalise.
However, Didier Deschamps made changes at half-time, bringing on Kingsley Coman for the booked N'Golo Kante, allowing Griezmann to take up a central position alongside Olivier Giroud in a 4-4-2 system.
The tactical decision appeared to change the game, allowing Griezmann to score twice to seal a quarter-final place for the hosts. The Atletico Madrid star believes that the words exchanged during the interval were key to the 2-1 result.
"We didn’t play well in the first half and we said things in the changing room," said Griezmann, according to The Mirror.
"The coach said things, the players said things, and we worked it out. We were playing for France though, so we gave everything and fortunately we got the result."
Deschamps revealed further details behind what was said, admitting he raised his voice in an effort to get his point across.
He said: "I raised my voice. We needed to keep calm but also to shake them up a little bit.
"The players... even some of the players who were on the bench were talking. That's because we have a good group here."
France will contest the quarter-final at 8pm next Sunday but will have to wait until Monday night to find out their opponent.
They will play the winner of England v Iceland.
