Here we see the Children of the Corn FC Metz Under-15 side showing off their new training drill, a hypnotically choreographed warm-up wherein the youngsters line up in formation and juggle their SenseBalls in eerie, nigh-on perfect synchronisation.
In fact, it looks like something from a North Korean propaganda film..
The SenseBall is a training aid developed by CogiTraining that is designed to help young players improve their balance, technique and “high-speed precision leg movements”.
In short, it’s a football on a string.
