Nik, nice first try.
I think: You need (very) hard drills, because Teixeira was a 6* player. My test was with 5* (98%) 18.y.o "good" fast trainer. I also think, worldclass GK-Training makes a difference.
That's the reason, why I said, I'll try it next season on my own attackers, because they will be AFTER reset at 110%-120%.
My ST, 22 y.o. made at the beginning of this season only 25-45 points at old training (he was at 111%), but he gained nearly every training 3-5% until was 120%. After that, it slowed down to 1-3% per training. Now he is 138% without any powertraining, just my daily training and the games. I don't use greenpacks often, except less time between two games or a hard competition. I manage, that I'm at the moment on +50 greens (compared to season start), but I'm out of the cup at playoffs.
My T11-team gained since the beginning of the season ~30%. I have a few players on 8* now (140%, best is 145% <- this one made only 5% over the last 17 days), but at 8*, they gain nearly nothing. They only gain 1-2% on a (very) hard pro/worldclass 6-drill-training. This is the expensive.
I give you an example about a normal day:
I wake up at 6.00-7.00am, team is ~85-99%, make my first and second training. Play first game, check the upcoming opponent. If he's weak,inactive,... I make another trainingsession with all player. If he is strong, managed,... I just make the training for subs. After second match, I check the time of the next game and the % of my players. If they will be full rested before 6.00-7.00am of the next day, they will be trained before I go to sleep.
My morning session: warm-up, stretch (or carioca with ladders), pass go and shoot (or 1on1 finishing), skilldrill, piggy in the middle, use your head (or video analysis).
My "normal" session for attackers: 1on1 finishing, GK Training, shooting technique, fast counter attacks, slalom dribble, set-piece delivery (sometimes I put "press the play" in)
First two drills are always the same. Following four drill I change and mix up.
My "normal" session for defenders: video analysis, GK Training, press the play, fast counter attacks, stop the attacker, hold the line
Also first two drills are always the same, others are mixed up.
My "late night" session is an easy training, always with long run at last drill.
Maybe this help. I'll post the results of my test next week.
