Atalanta is in sublime form, not too inferior to Inter. Currently, Atalanta is standing very firmly in the Top 6, and if they win this round 21 make-up match, they will even rise to take 4th place from Bologna. However, besides being a guest, the disadvantage for Atalanta is that their confrontation record is not good against Inter. Surely, Inter continues to prove its strength. But that doesn't mean Roma can easily benefit from taking the 5th position. Roma should prepare well for their upcoming match against Monza. They will only have a chance to surpass Atalanta if they win their matches.
Atalanta is indeed a quite strong and consistent team, but what they are facing is Inter Milan, which also has greater strength than Atalanta.
I realistically see that Atalanta will not win points in the match even though this match will still be fierce.
In terms of position in the standings, I don't think it will have a big influence even if Atalanta loses and even if their position is displaced by Roma, it is very possible for them to reclaim it as long as Atalanta can be consistent.
The difference in points is not that big and there are still a lot of matches left this season so there are still many possibilities that could happen.
