Goalkeeping Power Training,

[talisman]

The training drills upgrade on an even basis. You can only upgrade the drills offered to you, so you can't selectively choose to upgrade, say, Goalkeeper Training to World-Class without going through all the drill upgrades offered.

I have a Level 20 team whose Training Level is 71 and Goalkeeper Training WC upgrade was first offered when they achieved Level 70, after having several others upgraded to WC level at previous Level-ups. AFAIR I didn't get my first WC upgrade until I had all the other drills on at least Semi-Pro level (2 whistles).

The Goalkeeper Training system works pretty well at lower levels, too, as long as you don't over-do it. I've power-trained a couple of young players (18/19-yo) for my level 2 team using the GK Training, but only from high 3* up to low 5* level, and not used any more Green packs than at higher levels getting a mid 4* player up to low 6* level.
