It's all entertainment and hyping up for the next game, which we have not seen that much of except for a few cases. I don't know why it wouldn't be good for this time, they're deliberately making themselves sound cocky to hype the next game.
You've seen ALEX's interview on HLTV, he doesn't talk like that. It's just an act lol
Cloud9 are built to be the best, that's the entire thing around this roster, cs in general is more fun to watch with those cocky tweets around it.
also hampus said quick 2-0 pre match he deserves to be slapped
