I played a league game today (won 4-0). My opponent started with a 3-2-3-1-1 formation and the first half was pretty even. But in the second period, he had 2 players sent off (ML & MR), leaving him with no wide players. After that my team took control and scored 4 times.
My query is, did I just beat him through strength of numbers, or was he penalised for an illegal formation?
