Best defence of freekick? French club put goalkeeper in front of wall... and it worked

These cats might be on to something here. 
The reserve team for Ligue 1 side OGC Nice came up with an innovative defensive strategy on free kicks against Grenoble on Saturday, lining up their goalkeeper IN FRONT of the wall, which took their goalie's place along the goal line. 

And the results of the test run? Absolutely brilliant!

It worked!
This is way easier to pull off in the reserves when the free kick taker can't pick out the corner, but shhhh.

IT WORKED.
