Yeh this is the biggest issue for me, they should surely impliment some sort of possession lose for the lose of a player? I had a similar game. No injuries or sending offs but i was winning 3-0 at the end of the first half, he never watched the game. second half i changed some tired players (was like for like straight swaps, much the same quality, 2 players) and ended up conceding 4 goals and scoring 1 to draw 4 each. Surely , even if the 2 players had bad games, i shouldnt have conceded 4, considering his players would tire as the game goes on?
