If I was Messi, I will just rest because he will have no points to prove at this moment. He is only going to fall his hand and demolish the reputation that he built earlier in the last world cup. If there is anyone that will be hunting for coming back and making history now, it should be Ronaldo. All the clubs he went to, he made sure he made his marks there and the only team he's having challenges with delivering which doubles as the team he should be passionate about is his national team, Portugal. So, I will be seeing Messi's effort in futility because I don't even believe he can win this time around the way he won in 2022.
Messi is a player with extraordinary skills; he's not the type of player a coach would dismiss. On the contrary, coaches would even beg him to keep playing because those skills of his are still unmatched by other players. On the field, he can coordinate all the players on his team and single-handedly decide the outcome of a game. Messi is good at set pieces, he has speed and can dribble at high speed, and he's not easily brought down.
Messi scores goals, and he's a specialist in providing good assists. Obviously, Messi is the star every coach wants on the field at the World Cup. It's not about whether Argentina will win the World Cup or not, but rather that Messi can greatly help Argentina. Cristiano Ronaldo is a good player and very popular; he surpasses Messi in terms of popularity. But he doesn't surpass Messi in terms of skill.
Some people who are fans of Ronaldo prefer to close their eyes when it comes to comparing Ronaldo with Messi, but the reality is very obvious: Ronaldo has more popularity and Messi has more skill. There are still no players who do everything that Messi does.
