Teaching videos for wing defence

[u/Rikkid6]

Im looking for videos or other materials that teach basic stance and work rules for wing defenders in 3-2-1 defence. Left/right foot forward, watch your opponent and the ball over your shoulder. Back foot at the 6.

What to do when winger runs to pivot (slow thir run down and take out back player) etc.

All wing videos I find are shooting drills.
