To be honest, I didn't watch the Genoa vs Juventus match but if I heard your statement it was really sad for Juventus. They are in good form so any win should be theirs. But unfortunately the match ended in a draw which made Juventus fail to gain Inter's position at the top of the standings.
I don't know for sure what Juventus experienced but at least they didn't lose in this match and despite the polemic in Serie A, we shouldn't be surprised by something strange because Italy is always known for having several important people behind it.
I only know that in the last 4 games there are
3 missing penalties for Juvenuts
2 missing red card for opponents against Juventus
2 regular goal removed
3 gifted penalties for Inter
2 missing penalty for opponent of Inter
1 missing red card for Inter
Can be a coincidence but the path is clear.
