The 1998 world champions have had plenty of problems in their opening two matches - a draw against Uruguay and 2-0 loss to Mexico - and their troubles spread to off the field yesterday when Nicolas Anelka was sent home.
The Chelsea striker was disciplined by the French Football Federation after reports of his dressing-room bust-up with coach Raymond Domenech were leaked to the media.
It puts Les Bleus under further pressure ahead of their crucial match with the hosts, which both sides need to win comprehensively and hope there is a victor in the Uruguay-Mexico match.
Modise, who has faced heavy criticism for his own performances in the Bafana Bafana jersey, is now desperate for a turnaround.
He said: "I am not unhappy with my form this year for Bafana Bafana. I was happy with my game in the opening 1-1 draw against Mexico, but not so happy with what I did when we lost (3-0 to Uruguay). I know I need to play better against France."
Assessing the French team, he added: "We are not focusing on any individuals. We are concerned about ourselves and how we are going to beat France. We still have plenty of self belief and confidence that we can finish the group stage with a win."
