My prediction, Chelsea and Al Hilal will successfully advance next. If Al Hilal I agree with you, I also doubt Fluminense when facing Al Hilal, especially Al Hilal is very confident during the Club World Cup journey, they managed to hold Real Madrid to a draw and beat Man City, of course this is a good capital to beat Fluminense.
In addition to the high confidence after they were able to hold Real Madrid to a draw and beat Manchester City, Al Hilal must be obsessed with the amount of money they will receive if they qualify for the semi-finals. During the group stage, Al Hilal never lost. While Real Madrid won twice, Al Hilal only won once but drew twice.
The match has already taken place.
While Chelsea against Palmeiras, I am more confident Chelsea will win this match. Indeed, the Brazilian teams that appear in the Club World Cup also have the same quality as the teams from Europe. Indeed, so far Palmeiras has never lost, and of course they will make it difficult for Chelsea.
Chelsea is also not sure for me to predict that Chelsea can beat in normal time or in the AET because Palmeiras is eager to make the remaining Brazilian representatives to the semifinals.
I have no interest in this match.
