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.
If you look at the previous season Juventus is very powerful in Serie A. That is why I am confused why Juventus is said to only get good luck in that season, even though it is clear that they always do in Serie A.
They are the strongest team in Serie A and they bought Cristiano only to win the Uefa Champions League.They are used to winning the Serie A often and they are the team with the highest number of Serie A titles.
They will try again to win the Champions League this time.
