Watch my league game today in the analyser.
You will see my number 12 in the right back position. He was taking the place of my number 16 who was suspended.
My sub rules state that at 65 minutes number 16&3 swap (alternative formation 1) and then number 3 is swapped for number 12. So number 16 has moved from RB to CDM, and number 12 in my new RB.
Because number 16 was suspended, number 12 was already on. Number 3 still moved to RB but had nobody to swap with so for the last 25 minutes I had two players right on top of each other...
Clearly when there is a suspension then the rule should be voided. Yes I know I could have changed it before the game, but I shouldn't have to...
