question abou SA Interception & Football Union Options

[flower7]

Interception - for field players. The higher the value (the player who takes the ball), the more chances to take the ball - much to fast balls (blow). this one wa post by the rock.

I have read about special abilty but still dont get much about interception, is there anyone could expalin this statement with simple and plain english about this Interception abilty, suitable positions to receive this kind of special abilty are for midfileders, defenders, or forwards?

The second question is, what are advantages from joining Football Union?

i would appreciate if there any suggestion about my questions.thx
