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

exact becomes very difficult (because they are all within a few points) and it becomes fun because the teams will be hungry for points and therefore victories
so the games will be more fun
and i am more happy ahaha
Roma still has a very good chance of finishing in the fifth position but for that to happen Lazio needs to lose otherwise Roma will not be able to get past them.
Roma has two matches left in the season and they are against Venezia and Torino. I believe Roma will win easily against Venezia but against Torino, it will be hard. On the other hand, Lazio has 2 matches against Juventus and Verona. So I believe Roma has a good chance because I don't see Lazio winning both the matches that are left.
