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.
No team wants to lose, they have to lose. After the defeat against Brazilian club Flamengo, Chelsea will definitely take some precautions and will take on Palmeiras with a full strength team. No one will leave anyone out in the fight for the top 8. We are putting Chelsea ahead to win because we are familiar with Chelsea and see them as a strong team. We are trying to ignore Brazilian clubs because we are not very familiar with them, but in the end they have proven themselves. I am still not sure about Chelsea's victory, because Palmeiras is fully capable of beating them.
