Individual Training Planner

[Half-timer]

Here's a list of all key skills and all "clean" drills (that don't train grey skills) for every single position. And also leftovers -- key skills that you can't train to this position without training at least one grey skill. If your player has several positions, he also has key skills and clean drills from all of them, plus probably a couple clean drills more. Use ITP if you wish to know all the clean drills for any combination of positions, and stuff.
Goalkeeper Training drill is good for everyone, so I don't include it.

GK
Clean drills: Set-piece Delivery, Wing Play, 1-on-1 Finishing, Defending Crosses, Hold the Line
Leftovers: Fit-

So Goalkeeper Training isn't recommended for efficiently training a goalkeeper?

I usually train my entire squad together with a broad regimen which doesn't include Goalkeeper Training (because it's illogical to train those skills to outfield players), although occasionally I do focus on individual positions / players to give them a boost, in which case my keepers do GT. So I'm even more baffled now as to why my goalkeeper of about 5 or 6 seasons, who is rated at 6 stars (100%), has such poor goalkeeping skills but great Fitness and Communication.
