I have to say that I really like the team Fluminense is building for this year, on paper it's a team to battle for top 6, or even top 5. I think they can challenge Sesc Rio in Carioca Championship.
It's certainly a better team than previous ones, but I still see the big 5 + Barueri as better teams. I'd expect them to finish at 7th place at least, which I guess is an upgrade after not reaching the playoffs and almost being relegated lol
