There will never be a perfect system, there are still mistakes made in other sports that have replay (the NFL especially), but there is ZERO excuse that technology isn't used in goal line circumstances. Plantini had to want to throw up when his precious little linesman standing 5 feet away didn't get the call right. It's apple and oranges when comparing offsides calls to goal line calls, getting an offside violation right from 40 yards away and when the offender is barely inside the opponent half isn't near as egregious calling a ball a goal or not. Yes, the flow of the game would be interrupted, but it would happen very seldom and should be implemented.
Aside from that, hat's off to Roy. They might not lead in style points, but the squad has bought in and to win the group is quite an accomplishment. He'll need Young and Milner (if he keeps starting) to raise their games to beat Italy.
