To be fair, Miami is of course a team that faces simpler teams and scoring hattrick there is of course simpler to do compared to world cup where he will face the best players in the world. However, that doesn't change the fact that they have nobody better than Messi anyway, so even at 2026 he will still be the best player for his position and he will still contribute a lot.

Do I expect Messi to play and score three goals in any game during 2026 world cup? Of course not, I expect him to barely score three goals all together, but even when his stats do not show, he may still help a lot but drawing defenders onto himself, which is why it's such an important thing for everyone to keep Messi doing what he does, it will always be important.
