Yes, currently they are "dominating everything", especially Palmeiras who are having an incredible season!
It's a possibility, Palmeiras can win Libertadores and Flamengo maybe the Brasileirão!
Let's see how these teams will perform during the year
I forgot when I wrote, but Flamengo can win Copa do Brasil too, the team is on semi-finals, and the team is good enough to play 3 different championships at the same time ( Brasileiro, Copa do Brasil and Libertadores ), there's plenty of players, it's different than Bragantino, America MG and Athletico GO, these three teams can't hold 2 championships running together.
Since before the championship has started, Palmeiras was already the favorite. I imagine gamblers who bet on Palmeiras back then must be really happy with their progress right now. This time the most obvious team was the right choice. No surprises in Brasileirão this year. The question is, how long is the overweighting supremacy of Palmeiras going to last in brazilian national soccer?
I thought at the beggining Flamengo was the favorite, but it started bad, only now team achieved 2nd place, I think it's too late to get 1st place because Palmeiras have 9 points ahead.
Why I think it's hard?
It means Palmeiras have to lost 3 matches, and other teams (Flamengo and Corinthians) have to win 3, only to have the same points
With this consistency, it's hard to not bet on Palmeiras on this Brasileiro.
