If Juventus loses to AC Milan then actually Juventus' position will not be shifted and will remain in 6th place. It's just that AC Milan will get closer to 6th place. But if Juventus wins then Juventus has the opportunity to move up to a higher ranking. If one of the top 5 teams experiences a draw or defeat.
Napoli who will face Roma may be more difficult to predict. Although Napoli can still be the favorite because the difference in strength between Napoli and AS Roma is quite different this season. AS Roma are still inconsistent and are still experiencing a decline in performance until their last match. It's just that in the match against Napoli there will be something different. Because AS Roma will make its debut with its new coach, Claudio Ranieri, who has returned from retirement just to try to save AS Roma and fill the vacancy on the temporary coaching bench at AS Roma.
Yes, it is true that Juventus' position will not be shifted by AC Milan even though Juventus suffered a defeat this week. Because the point difference between Juventus and Milan is 6 points. So it takes 2 more defeats from Juventus so that Milan can overtake Juventus' position in 6th place. Well, expecting Juventus to lose when Juventus has never lost this season is indeed difficult. So it could be said that Milan is not so lucky this season. Their journey with the new coach does not seem to be as smooth as expected.
For Napoli's match against Roma, we can still be quite confident in favoring Napoli. Because in this week's match Napoli will even be the host which will give Napoli an extra advantage. Maybe the best result for Roma in this match was just a draw. I can't imagine Roma can win that match with their current condition.
