Yes, there's a 99% chance that these three will be the top three, which is why I narrowed the list down to three, hehehe
But what do you (and everyone else here) think the final standings will be at the end of the championship?
Just out of curiosity, take a look at the list of the top 3 from the last 10 years. Only Braga in 22/23 managed to stay ahead of one of the top 3

I totally agree with this analogy, it's not even far fetched the evidence is right here. The Portuguese title is just circling mainly between these three teams as stated here in the last 10 years and it will still happen again this new season and there's no doubt about that.
