if you don't have time for game. your plan is good, you can play 5-10 minutes a day ....
i can't understand why people say 2 match a day is too much for them. I play at least 4 match a day(5 in the day i have only league match) and have no problem( i don't buy any green pack) may be my squad is 20 so your 11 players can play at least 2 match ?
gain from competitive match is 30% more than in hard trainning for sure (gain from friendly match is 30% less than hard tranning)
