I suspect but can't prove a player used cheats, should I report it?

I used the appropriate formation and subs, as I have done from 25 seasons of learning. Favorite doesn't always win, except I was the favorite and also prepared my team to the max. I am highly doubtful that tactics was the problem, unless the game engine suddenly changed.

Stephen try look at your oppo past matches in cup. I think he is well prepared too and maybe he knows what he is doing. Or unless like you already say the engine troll you. We learn everyday. cheers!
