Definitive Illegal Formation Rules

[Accyrover]

Someone like to comment on why this formation was penalised with 20-80 possession.
I cannot see anything that seems to infringe on the current known guidelines if illegal formations.
All players are in their correct positions also.
Possession remained constant for the 90, no H/T in this match. I was ready to make a sub as some players had not recovered from a late game last night, the game clock went from 44min to 52min.
Also another manager joined the game on 12min supporting me, not a clue who he is, made no difference to the possession so I suppose 80% is the maximum the engine will allow.
