This tournament is not for the Europeans. It's a big world out there, even football is not all about Europe. This tournament is a pretty big deal for the other continents. The South Americans relish the opportunity to face the CL champions, the Mexicans really wanted to show the world they are big time. Just making the finals is a big deal for all but Europe and South America. I expect Kashiwa will be going all out to try to win the 3rd place game.
Lots of teams rough it up against Barca, the only advantage they have is that they are bigger and stronger. If anyone in the world has reason to complain about getting fouled, it's Neymar. He is so dangerous, so elusive and so incredibly thin that defenders just try to break him.
