Palmeiras' next step in the quarter finals will be difficult when they have to face Chelsea. Previously, they did not face strong teams that were favored in this competition. But their performance was not bad, even holding Porto and Inter Miami to a draw. Palmeiras may not be favored in the next match, but I agree with you, they will definitely make it difficult for Chelsea. There is a worst possibility for Chelsea in the quarter finals, because they were also defeated by Flamengo, so a surprise might happen.
I don't even see them challenging Chelsea, they are good quite alright but Chelsea is far from their level and I don't see them giving Chelsea a hard time. Chelsea have improved quite a bit so they should be able to win the game without any pressure.
Hopefully, like that, and we can see the semi-finals that will be dominated by top European clubs. It's just that I'm talking about the worst possibility and the situation that causes drama in the match. If Chelsea gets a disadvantage at the beginning of the match, the situation will definitely not be good for Chelsea until the end of the match.
Hopefully that doesn't happen.
