BAD DAY vs TROLL RESULT
Let's examine in the lab some results from some games (it's from my friends)
Bad day
A friend of mine with his team PIERIKOS, playing in the top of the server.
He has a very good team of 7* players but the first team of his league, Liverpool, has a 9* team
Although, he was the only one who managed to get a draw against this super team.
But in another game, playing vs the last team of his league (a 5* team), he lost.
The process of the game was weird but it can explain as a bad day for his players and a good day for opponent players who where more effective plus a good performance of his GK. Very frustrated but can happen.

In another league of friends, there is a team (Kali) who is struggling to stay in the same level.
So, he use this "illegal" formation.
In this game playing with a friend, he managed to get a draw

and in another game, playing again with another friend, he had to switch another player with his GK and didn't make a sub in his injured player so my friend
managed to win the game with 3-2

Well, that's a troll. With no football or game logic, the calculation of the game totally ignored the formation and the position of the players.
Ok, it's not very common but can happen 1-2 times every season and it's something that must be fixed.
