First of all this "Yes, I know all game results are decided by Top Eleven." is not true, the game results are decided by your tactic, players, home or away, suporters and yes i know sometimes the game engine it's kinda stupid but hey there are 9 milion teams so it's hard.
And if you have games so close don't use your rest pack's, if the players have condition over 60* or try to change some players , trust me i play a lot of games one after another and i didn't use my rest pack's and the result was good.
