I agree, Rome's chances will increase a lot. In fact, at the moment, the probability of each team placing in each ranking remains. It is very difficult to predict which team will place 5th and which team will place 6th.
But I also think Roma and Lazio will share these rankings. Lazio can earn 1 point after the next match is drawn

Yes it is so tough to predict that who will get the position of 5th. Both teams are almost in the same condition. Roma will try to get the position but Lazio is also good enough to uphold their position. It will be a tough game for Lazio against Juventus.
