With Messi moving to Miami , I do have confidence that he will be playing at the next WC , especially that he will know all the pitches by then and having extra info even if the age won't forgive Messi but I would like to see him playing one more WC. Now , can Argentina win it again ? I doubt it because believe it or not , England looks the strongest team on the planet right now , because they do have a lot of young talented players with massive experience in both WC , EC but also UCL and Premier League.

Sounds like a fantasy but I'm pretty sure that in the next World Cup we'll probably see both Messi and Ronaldo - even if they are mostly benched and all their playing time is limited to group games (which will obviously be easy). They are huge brands and I think even the organizers will push the leadership of the national teams to see them at another World Cup.
As for the "strongest team in the world - England" it's probably a joke

I'm just imagining how the state of performance of Ronaldo and Messi will be in 2026 World Cup, I don't think they'll be very active their games and they won't be a player that can be rely on .so this means that if at all they will still be playing in the World Cup tournament they will not be given more chance to play in every game.
