"The brighter the area, the better the possession" (and no names over the players)

[Tyltyl]

So, yesterday I left my team with every player in their wrong role, and this is what I saw today.
Apparently, even if you place the players out of their position you still get possession according to this new system. I thought you lost possession if you placed your players wrong with a red warning sign?
According to Mourinho, I'm strong in defense with ST and AMC
Also, why no name tags or roles over the players on the pitch??? This is NOT clear at all! I don't know who I'm moving and where I can place him!
