I think we will have an uncertain World Cup and it's really difficult to predict the winner. I give a slight advantage to the French, they have a dangerous team full of players who play at the highest level, Mbappe, Pogba, Griezmann, Kante, Dembele, Lemar, and Benzema, who is having an excellent year, he can even take the title of the best scorer. He took that title in CL, maybe he can do it again?
Never has history about national team success become the winner of World Cup in a row after several edition time always have different national team become the winner, lets feedback at 2002 Brazil become the champion and next time edition Italy success become the winner. Four years later at 2010 have new champion of World Cup Spain. Edition on 2014 Germany success become the winner and last four years ago France success win after beating Croatia at the final.
No doubt with France player composition, but I am believing with myth never have the same national team success win World Cup in a row, seems have another national team get the winner in this edition except France.
If you only look at recent history, then you are right, but if we look at the entire history of world championships, then we already had examples of Brazil and Italy being world champions twice in a row.
And as far as recent history is concerned, in the period 1994-2002, Brazil played three times in a row in the final of the world championship and was twice the world champion.
I personally think that France, along with Brazil, has the best team at the world championship in Qatar and I see France as the main favorite for the world championship title.
Of course, surprises are always possible
