On paper Empoli is not better than Juventus, in fact they have quite significant differences in my opinion, but that does not mean Juventus can underestimate Empoli, they must remain vigilant against their opponents this week. Empoli is unbeaten in the first 3 matches, although they only managed to win 1 match. Likewise with Juventus, they won 2 times and drew 1 time in the first 3 matches.
It's exactly on paper that Empoli is better than Juventus, because in your own words, they beat Roma away while Juventus didn't manage to score a goal against Roma at home, so exactly on paper Empoli would be better, more when you look that Juventus has a really a bad stats for away games, one out of nine, so based on that no way Juventus would be a 1.72 favorite away..
But that's exactly only on paper!
Not worth the direct bet, if you're confident in Juventusyou can take -1 at 3.2, more value for the risks.
