When I made substitutions, I wanted to take out Pogba, who was my lowest scoring player, and put a defender on. So I subbed him off, and changed my formation from 3-4-3 to 4-3-3. The game automatically then subbed off Valbuena from my midfield, leaving me with an empty spot in midfield as well as defense. Horrible system. Also, the points seem so illogical. I got 6 points with Alba.
