This is apparently a training exercise at the French national soccer team's camp.
What use it could possibly have on the pitch is tough to decipher. Maybe they are working on a devastating new double flop designed to get as many opposing players red cards as possible? Or could this be a method acting exercise where they try to understand what it is like to really "be the ball?" Perhaps the French practice facility is next to a colony of Amazonian fire ants?
Considering the team's 3-0 trouncing of Honduras over the weekend, whatever they are doing must be working.
