If Juventus stays on a winning track for the rest of the season, of course they still have a chance to get into the top 4, I think this is a good chance for Juventus even though they are penalized with a 15 point deduction and no chance to win the Italian league this season. at least being able to qualify for the UCL next season is good enough.
In terms of the opportunity for the top four positions, it is still very possible for Juventus in terms of achieving it, because in the near future Juventus will not meet such a strong team, namely Verona, except for Lazio. Because the most difficult opponent for Juventus in the remaining matches in this season in Serie A is Napoli, and apart from that Juventus still have to hope that three other teams such as Atalanta, Roma and Milan can lose their matches. So that the victory obtained by Juventus is not in vain (if Juventus gets it).
In my predictions for the three teams you mentioned, such as Atalanta, AS Roma and Milan, it looks like indeed it will be difficult for them to get consecutive wins. Also, if for example Juventus can finish in the top four then it's not a pretty good result, but a very good result because to come back from a slump like that is not easy.
So, in the remaining Serie A matches, if Juventus can consistently win or don't lose, then the chance for Juventus to be able to continue to rise in the Serie A standings is very likely to happen.
