Yep the ET period means: the winner of the period wins, a no goals scored draw means penalties and a scorind draw means a win for the way team.

FWIW, in ET the home side have home advantage and the away side have away goals rule. Same as irl. T11 programmes in the home advantage but its easier to subvert it than it is irl (even if there is such a thing in either) so its questionable.

But its easier for them to take UEFA rules off the shelf
