U.S. men’s national team coach Mauricio Pochettino said he will integrate new, young faces into the program in the upcoming international window, but also sent out a warning to young players to approach their careers with humility.“We are watching everything, we are seeing everything,” Pochettino said.Speaking with a small group of reporters Monday, Pochettino was asked about how he feels seeing so many young players thriving in MLS this season and a lot of them saying they want to be a part of the national team. While the U.S. coach did not mention Cavan Sullivan’s name, Pochettino’s response felt pointed toward a recent interview the Philadelphia Union’s 16-year-old winger gave on Alexi Lalas’ “State of the Union” podcast in which he said could have made an impact at the 2026 World Cup.“We are very happy to have all these potential good players,” Pochettino said. “Being young, and with a possibility to perform and to play. Only we need to be careful, no? We need to be careful because when you are young, of course you need to be confident. You need to have the trust in yourself and believe that you can perform and you can do well. But I think there is a limit.“The balance is the most important. And one of our responsibilities is to protect these guys because sometimes, if you play well and you are 17, 16, or 18, and you play well and people start to talk (like) you are (Leo) Messi, or you are a big star in the world because you do a few good things, if after you are confused and you don’t manage (it) well, that can be dangerous for your career and that is what we don’t want. We don’t want that (for) the young guys with potential of being top players.“(We want) to provide the platform for them to evolve and to be professional, to build their career in the best way, improving every day, being humble, being careful when they talk in the media, when they talk with their teammates, when they talk with the opponent. I think respect is the most important thing, and they need to be respectful.“And of course, we want players with talent, players that feel brave, feel confident, but not (that) feel things that they still don’t show or they (haven’t) earned. I think you only are entitled to talk a little bit out of order if you are Messi. If you’ve won eight Ballon d’Ors, OK, you can talk with a certain arrogance. But even Messi, never are you going to hear him talking in this way. But if you are young and you start to talk that you can play here, you can play there, or you can play, I don’t believe that these are in a right way to build your career in the best way.“And that is why we need to be careful.”Cavan Sullivan has had plenty to celebrate in recent weeks with a surge in form for the Philadelphia Union (Mark Smith / Imagn Images)Sullivan, 16, has been fantastic in MLS this season. With a goal in a 2-0 win over Montreal on Saturday, the winger became the first teenager in MLS history to register a goal contribution in five consecutive games. He also passed Freddy Adu for most goal contributions by a player 16 or younger. But he has also been put front and center across multiple marketing campaigns and has been referenced by MLS commissioner Don Garber, among others, as one of the best teenagers in the world when he signed a deal that will see him join Manchester City when he turns 18.In the podcast interview with Lalas, Sullivan was asked if while watching the World Cup he dreamed of performing in 2030.
