GK has 11 white skills, with only fitness being common with all out-field players. Unless you are power-training a FT, usually you would not train fitness as all drills would involve fitness with other unneeded grey skills for GK.

Just focus on the drills where there are only white skills. It depends on how many drills you have learned, and try to focus first on those drills where it is of a higher level for better efficiency, then the rest when the stronger whites are increasing slowly.

Eg. Set piece delivery, Wing play, 1-on-1 finishing, GK training, Defending crosses & Hold the line

If with 1-on-1 stopper SA, 1-on-1 finishing could be best to further boost up anticipation and rushing out; if with PK stopper, GK training could further boost up agility and reflexes.

Hope it helps.
