I generally don't do any training to any of my players that play 2 matches a day, yes you will play 2 matches a day if your involved in all 3 competitions. And put my main teams on rest, then with the other players that didn't play or made subs I train until they are down to around 60% condition meaning the next days fixture my squad is anywhere between 90-99% condition and ready to play 2 competitive games in that day, I would use green boosters for 2 reasons, when you have important game and to conduct some power training.
