Didier Deschamps said he never doubted Kylian Mbappe after his return to form in France's last-gasp win over Belgium in the Nations League semi-finals.
Mbappe scored a penalty as France completed a stunning Nations League comeback in Turin on Thursday, overturning a 2-0 deficit in a 3-2 triumph en route to the final thanks to Theo Hernandez's 90th-minute strike.
All eyes were on Mbappe after revealing he considered taking a break from international football following France's Euro 2020 disappointment.
Mbappe missed the decisive penalty as France sensationally crashed out of Euro 2020 at the hands of Switzerland in the round of 16 but the Paris Saint-Germain star assisted Karim Benzema's goal before equalising with his 69th-minute spot-kick.
Afterwards, France head coach Deschamps hailed Mbappe, who became the youngest player to reach 50 games for Les Bleus (22 years and 291 days), overtaking Benzema (24 years and 240 days).
"Kylian [Mbappe] didn't have any doubts," Deschamps told reporters. "I have always been behind him, I saw his determination. He was full of good intentions during the Euros, he missed the efficiency in the end, but he was injured, he couldn't play the second and third game.
"There are a lot of expectations with Kylian. I've always said this, and it's not to be nice, I know very well France is a lot stronger with Kylian. Today he did it.
"Offensively, in his efforts, the way he is complementary with Benzema and [Antoine] Griezmann has added to that. It's good for France. But I never had any doubts about him.
"It will have been good for him, definitely, on a personal level, but since he arrived at the start of this week, I could sense that he felt that it was an important match for him as well, and all for the better for him and for us."
Hernandez's thunderous long-range winner meant world champions France claimed their first victory after trailing by two or more goals at half-time since May 2012 against Iceland in an international friendly.
Belgium had led 2-0 at the interval thanks to Yannick Carrasco and Romelu Lukaku but France will now meet Spain in Sunday's Nations League showpiece.
"It's the kind of football that we like when we end up on the right side of it," Deschamps said. "It's amazing to go from one emotion into another in a big game like that, against an opponent like that. We were on the wrong side of it this summer, and it hurts.
"It's hard, I put myself in Roberto Martinez's shoes when it comes to the final scoreline, it hurts. But you have to accept it. Much joy and pride, I'm here for that. I've known many great moments, and we're going to have more. Because the quality we have in this side, the spirit, the mentality even if we had to react to the situation. But to be able to turn around a situation like that, I can only be proud of what we've done tonight."
