I'll not make my prediction yet but I do think it will be a Portugal vs Argentina quarter final and the outcome will decide if Messi or Ronaldo gets the balon d'or for the 6th time.
Going to see 5 matches in the following order,
Iran vs Morocco,
Germany vs Mexico
Poland vs Senegal
Portugal vs Morocco
Argentina vs Croatia
The Argentina match is the last of their group games so it will be a big match. Looking forward to seeing Messi and Ronaldo in person.
