need a formation for 10 days as im not gonna be present?

[Nihal Manzoor]

How does any legal formation, with injuries or red cards, go into an illegal formation.
I thought that the engine substitutes the player until there are no more players to make a legal squad of 14. Until then the formation remains in play.

So, my question is, why is 442 the best play, even though we have absolutely no idea what his strengths, depth or weaknesses are?

yes i also have the same ques as when there are injuries and red cards how can a legal formation be an illegal and yes i have a good defense and also a good attack
and this is my team and formation for few games
