Scotland is on top of Euro 2008 qualifying Group B with nine points.
McFadden said: “It’s the best result that I’ve been involved in during my career, not just with Scotland.
“It was a great result and keeps us top of the league and further away from France and Italy.
“It was even better than when I scored the winner against Holland in the 2004 play-offs. France are probably the best team in the world at the minute and if they are not the best then they are one of them and so we are absolutely delighted to get the win.
“It was great in the dressing room afterwards. It wasn’t a great performance but it was very effective and we are absolutely delighted.”
