I have very little time in the mornings to set my teams up for the day, so I need to get the formation setup and daily training (for match bonuses) done as quickly as possible.
I use these drills
2x Bonus used for two training sessions (any number of players, as long as it's at least 8, including GK, def, mid and st) gets Condition and Possession to 10% and Attack and Defence almost filled. One training session without 2x Bonus (again at least 8 players) gets the A and D to 10% also. Overnight the % drops to 8 and start all over again.
Which players do I use? As many as possible - I set the team up first to counter the opponent, so I know the starting XI. Calculate how many recovery sessions are available before first match kick-off, and include the starting XI for that many (if any) otherwise use up the substitutes and reserves.
Later on in the day, after the last match, I have more time and can concentrate on individual and group targetted training then.
I use two of my daily videos on Match Bonus maintenance and between matches, if necessary, I use videos for condition recovery. If I have time, I'll harvest a few green packs using videos (I don't need to do this for red and blue packs as I have at least 1.1k of each of those...) Any green packs I pick up are accumulated and used for SA, additional position, and power training Youth graduates.
