It looks like in every Round of 16 match there will be one of the "big teams". This sounds like a normal thing but in previous World Cups there was always at least one 'underdog match' that enabled on of the underdogs to get into the quarterfinal. May it be Switzerland vs Ukraine in 2006, Paraguay vs Japan in 2010, Costa Rica vs Greece in 2014 or Sweden vs Switzerland in 2018... Let alone the crazy 2002 World Cup. Technically a R16 match between Morocco and Japan/Costa Rica is still possible but I really really really reconciled with our German team after the match against Spain so I don't want our journey to end that early again.
Anyway, surprising underdogs are the spice of every WC so I hope one of the underdogs will somehow find its way into the quarter final. I could see USA beating the Netherlands for example.
