Don't you think Chelsea must have learnt a severe lesson from their previous defeat to flamengo and would make all necessary adjustment to avoid something like that to happen again and moreover flamengo is probably the strongest team in the Brazilian league so their is that fact, so Chelsea might just have the upper hand in defeating them.
The problem y'all have is that you underestimate these teams and expect too much from a game, only to get disappointed with it. Chelsea shouldn't have lost to the flamengos then if that was the case -- but the truth is, we still don't know how well they've adjusted/ how penetrable their opponents defense will be.
Brazilian teams are built different and for whatever it takes, they'll score goals if they had to. I feel like Chelsea is not in the right form to go past this phase in this competition. I don't wanna lie to myself, but we can all see the pattern of play -- unless it takes a different shape tomorrow, Palmeiras will win and qualify.
