Last year Juventus was very lucky and apparently they won the title.
They won most of the matches with 1 goal scored and most of the times this goal was lucky.
I don't think that's good luck for Juventus.
If you look at the final standings that Juventus have 90 points and 11 points from the second place. Things like that are not luck, but juventus does win more matches in Serie A.
Sometimes things are not are they like.
I don't doubt the title that Juventus won last season. I am just pointing out the fact that they won a lot of games with 1 goal.
Personally, I didn't like the way they played football last season. But this is just my personal opinion of course. It depends on the kind of football everyone likes to see.
Last season Juventus did not have competition in Serie A. Other clubs did not provide resistance to Juventus, therefore Juventus have a far point in the last season. If what you say is about the luck Juventus has by scoring 1 goal, it's actually the luck that Juventus has.
