I don't think the system is like that.
Juventus' condition if they can't shift Roma they will still be in 7th place and there may not be a place for the Conference League.
I don't know for sure about this but still reflect on previous cases, especially for last season when Frankfurt automatically went to the Champions League because they won the Europa League, it was still counted and did not shift other clubs and representatives from the Bundesliga there were 5 clubs.
It is also possible that it will be the same but I don't know what will happen if Roma's current conference League slot and they qualify for the Champions League whether there is a change from another Serie A club (in this case Juventus) or not.
What is clear is that if Roma are able to become champions they will get tickets to the ucl next season and their slot will probably be a struggle in the final match of the European conference League where Fiorentina vs West Ham. well if Fiorentina can win the European Conference League then they will qualify for the Europa League next season so I think that's the scenario. So if you look at the Serie A teams next season competing in the Europa league, of course they have quite a lot of representatives if the scenario goes like I said earlier.
Roma is really focused on the Europa League Final to become a champion and they must be able to try harder to be able to beat Sevilla because this is the path Rome must take if they want to compete in the Champions League next season.
It seems that this scenario is very possible rather than looking for a position in Serie A especially for now Fiorentina and West ham also did not get that position so this is likely to happen and indeed this is still quite worth seeing the continuation because it is likely that the decision will occur after the final in the first week of June.
But it is also quite interesting now about the steps that will be made for Sevilla and Roma in the final because after all this is a fairly important slot because whoever the champion is also ensures that there will be greater participation in the Champions League next season whether it will belong to La Liga or Serie A.

The Europa League final is very interesting now because looking at the current odds, it seems like we are still very difficult but of course this is the best chance we have especially with the odds given by the bookie.
Stefano Pioli's men only need one point to secure a ticket to the Champions League ahead of the match against Juventus, but because in that match they won automatically they are very safe and no one can chase their points in the top four of the standings. The match against Verona will not affect any results for AC Milan, so Pioli can relax a bit and doesn't need to field the main squad and can instead try to play his youth squad.
I'm a bit surprised with the results, I think Milan will be lose on this match. Lucky for Milan, they can manage to win. Pioli need to do something next season, because if AC Milan still like this, maybe they wouldn't qualified for UCL. This season AC milan lucky, becasue Juventus get a sanction. As your opinion, Milan need to focus for better playing style for every matches.
Milan was very lucky due to the point reduction that Juventus had to accept. Then Pioli's troops were also able to take advantage of the situation that the Bianconeri were experiencing because their mentality was indeed down. Now for the additional three points, Milan's position has secured its position in the top four of the standings. The last match no longer affected Milan's position, Pioli was quite relieved by such a situation.
It was a well-deserved stroke of luck, not only for Milan but also for Lazio who are also feeling a bit inconsistent at the moment.
Now it only remains to wait for the last match between several clubs that do adjust their positions, especially for the 5-7 standings which are currently filled by Atalanta, Roma and Juventus, which is still very interesting to see how surprises in the last week of matches in Serie A.
