In the second half of the season, Juventus will actually be in a more difficult position. Because now they might win because they are playing as the host. But in the second half of the season, Juventus will have to face these strong teams again at their respective headquarters. Away games are usually more difficult than home games. And that's when Juventus will really be tested. Currently, Juventus actually does not have as good a squad depth as Inter Milan and Napoli. But Allegri is the one who always manages to make the Juventus squad perform optimally despite all its limitations.
I do not think that it would be all that chaotic, we are talking about a situation where Juventus is already better than 95%+ of the league, maybe Inter could be considered better, and only maybe and nothing is certain but aside from that I think Juventus is better, so away games will not matter. They may end up being good enough to just win the league all together and not have any trouble at all.
This is not sure thing, if they get any player injured then they may get worse and the results may not be good, but that will not be because home or away game difference, that would be because they may miss players to injury, if that doesn't happen and they are healthy then they are going to have a chance to win, and if other teams that are near their points end up with injury trouble then Juventus will eventually have even better results. This is why I believe that the best thing to do right now would be just focusing on winning the way they did all season.
