Football can always surprise and at the world cup in Qatar we saw very well how Morocco performed with above average quality. Germany, who had previously been seeded as champions, had to return home sooner than imagined and Luka Modric managed to create a nightmare for Brazil and what hurt quite a bit for Italy, who at that time did not qualify for the Qatar world cup, because they did not qualify in the preliminary round of grub.
Unfortunately I confess, this is true! lol Modric was onfire
An important point that was decisive for Croatia is that Brazil was extremely unresponsive after Croatia goal.
Brazil was destabilized and emotionally affected, especially on penalties
It's still quite a long time in my opinion and there are still more surprises to come, considering that there are still a few more years to prepare for 2026. Maybe the closest we can see is the Copa America and there also has a representative country which is quite extraordinary, because the Copa America too usually it will give birth to several new players in Latin American countries.
I confess don't have a definite answer
I believe... in 2026 it could be Neymar's last cup.
And I also imagine, the 2022 World Cup was the last one for Cristiano Ronaldo and Messi (although, they still have physical preparation and a lot of technique and skill)
