I'm happy to see Juventus race for the first place in the Serie A because I was predicting to see Juventus win the Serie A and I can even bet on this team because I'm totally sure that Juventus is in the good form enough and because of not playing in the Champions League like other teams do, they can have higher chance compared to Inter Milan.
Don't underestimate Inter Milan. They are also in a good condition this season. If we consider the squad quality, I think Inter Milan is a bit better than Juventus. However, Juventus can focus for the domestic competition, meanwhile Inter Milan has UCL matches. They also qualify for the knock-out phase, which means Inter Milan will have busy day in UCL against stronger teams. This is the advantage for Juventus because they only need to focus on Serie A matches. Their players must have a better preparation due to a longer time for resting. However, since Inter Milan is leading the table, they still have a higher chance to win it.
I agree with you that Inter Milan is in good condition this season. The squad that Inter Milan has is much better than Juventus. In fact, last season Inter Milan almost won the Trable Winner if they didn't lose in the UCL final. Indeed, Juventus does not have a busy schedule like that experienced by Inter Milan because Juventus does not compete in European competitions. But the depth of Juventus' squad is very worrying, especially if some of their core players are injured, it will be a big problem for them because the season is still long.
