Given how Mexico lost disastrously against Sweeden and barely qualified to round of 16 thanks to South Korea, it is most likely they'll be playing against Brazil. Moreover, I'll be honest to myself that Mexico, since USA 1994, is not going to advance into quarter-finals this World Cup. Hence, I'll prefer Mexico losing against Brazil rather than losing against Switzerland or Serbia.
I prefer we lose to a fellow Latin American team and the Champion of World Cup Champions.
