Right, my local network didn't allow my Portugal friend to watch the game and disallowed substitutions and the goal my team has scored. I think you just don't get that I'm not talking about regular connection problem.
This happens to me when someone arranges friendly. Your team doesn't get any boosters, but your players don't lose any condition and can't be injured in such games. This season all friendlies go just like that for all three my teams - you gain boosters and training progress only if you're the one who arranged the game.
But something is wrong if that was a Cup or Championship game.
