Is red cards illegalise the formation?
Yes, a red card can make your formation illegal and you'd get 20% possession from that point on.
e.g if you had 3 defenders, and 50% possession in the first half, and a defender was red carded in the 45th minute, you'd end up with 35% possession overall (50% first half, 20% second)
