Meanwhile, France which is currently without Benzema, is possibility will not win in this final, although the current French squad can't be underestimated, but against Argentina and Messi will be the toughest for them. Also usually I tend favorited France for win, but this time I'm going to switch to Messi with Argentina.
Why? France goes to the final without benzema and i see no problem for france against argentina in the final without him. I think that you're undesestimating france. It can be seen from how you are thinking benzema was affecting the france while he never plays in the current world cup with france. Let's see whether messi can perform offensive against france or not. France never become an underrated team for now. Mbappe may able to defeat messi and messi may go home without trophy. The most hyped match will be coming very soon. This will be a real spectacle, no doubt about that! Both teams deserved to be in the finals. The bookmakers give them equal chances, so it's difficult to draw any conclusion about who is the favorite here. The playing style of both teams is attacking, so I hope that there will be goals on both sides in this final! I wouldn't be surprised if see a draw and penalties, very nice odds for that!
I will stick with France:
I submitted my predictions and somehow ended with Brazil vs France in the final game. I chose France as the winner! 
I thought they would play against Brazil, but Croatia stopped them and later lost to Argentina... I was close.
