Talking about the best soccer team in Minas Gerais

Miller: Hello David, what’s up?
David: Hey Miller, not much man!  What's going on with? 
Miller: Ah, nothing really.   did you see the games over the weekend?
David: Yes, Cruzeiro won 4 to 1.
Miller: Oh that’s good, Atlético won 4 to 0. The rooster is always the best, right? 

David: Yeah right! Go ahead and try to convince me.
Miller: Ok, let´s go. The rooster never gives up and that is why he is known as “the avenger”.
Furthermore, now our main team is the best in Brazil!
David: Maybe that’s true, but who has more major championships?
Miller: Ok...Cruzeiros, but it's been a long time since the Cruzeiros won anything…
David: Unfortunately that's right, but this year we will win many championships!
Miller: Common man, wake up! Your team is so bad…
David: I disagree with you, now our team is one of the best Brazilian teams.
Miller: Haha… Are you kidding me? Since the rooster picked up Ronaldinho Gaucho and Tardelli we are the best!
David: Oh gosh… Rooster supporters trash talk so much! We will see who is the best in the next matches…
Miller: Ok, I’m anxiously waiting for it!
David: See you man!
Miller: See you, bye!

Haha very good :)  Red is corrections and what I wrote in blue is more natural!  Great job.
