Really, I was also expecting more from Fluminense, but that's how it is in football, the best team always tends to win, I'm going to miss this tournament, many teams with small investment (compared to the big ones) surprised, that's the essence of football, that's what makes it interesting.
This is first time a club level world cup is organised by FIFA and this gives opportunity for clubs around the world to play with each other and compare their performance. This time the title will be won by an EU team as Chelsea already in the final and waiting for result of Madrid vs PSG semi finals. We can expect that other teams will also improve their performance and play for the final round in next Club World Cup just like Morocco became the first team in 2022 to play semi final of FIFA world cup.
