Of course, Juventus has no proper squad to compete with Inter Milan. Moreover, Juventus players often got injury. Now, Dušan Vlahović and Arkadiusz Milik are injured. Sadly, Dušan Vlahović seems to take a break for a long time because there is no exact time about when he probably recovers. Without Dušan Vlahović, I'm sure it is difficult to win in the big matches. So, it is impossible to compete with Inter Milan, specifically when the point gap is already very large. The point gap between Juventus and Inter Milan is 17 points now.
I agree that the realistic target for Juventus is to finish in the runner-up position. However, it is not easy because AC Milan is leading with 3 points now. Juventus wasted too many points, so AC Milan could overtake them in the 2nd place. With the current condition of Juventus, I'm not really sure if Juventus can return to the 2nd place again. So, the most realistic target is to stay in the top 3/4 (UCL zone).
The league is still very much open between them AC Milan and Juventus ,and for any of the team to finish second in the Italian serie A league table, besides we are talking about 3 points here, a matter of AC Milan losing of one game and boom that will give Juventus the opportunity to move back into the second position in the league, Therefore, as it stands so, still never count them out yet on finishing second.
