Argentina (and Messi) will never have a better chance
Messi is already 27, which isn’t that old but imagine four more years of being kicked in the shins and he might not be the same in 2018. This World Cup also had many of the big teams fielding historically weak lineups versus a Leo who's pretty much at his peak–he will never have a tournament as ripe for the taking as this one.
Brazil will be unrecognizable
Except for Neymar, the Brazilian populace will probably want the entire current lineup kicked out–just like how the 2010 team was almost totally erased in the current lineup. Their non-performing forward line should be first to go–don’t expect Fred (DIVER!), Jo, and Hulk showing up in Russia.
Portugal fades into mediocrity
This Portugal team even wouldn’t be worth writing about if Ronaldo wasn’t in it. Remember: It was Ronaldo who singlehandedly got them into Brazil, during the playoff versus Sweden, in the first place. He’s already 29, and probably very discouraged about the future of this current squad, just look at his non-celebration of the “winner” against Ghana. Galit ka, mhen?!
