I've read the answers and your follow-ups as well. My question is "why do you want it?" I would guess it's because you are a fan of the USMNT and want a different way to show support for individual players. If that's the case, I would not care about whether the player is established with his team or likely to stay with that team long term. If you were a Dortmund fan for example, then getting a Dortmund Pulisic jersey could be a risky investment going forward. But as a USMNT fan, I would not care. He wore the Dortmund jersey. Who cares if he's on another team in 6 months. You're not wearing the jersey because of Dortmund you're wearing it for the player. I would concentrate on the combination of a player and the look of the jersey. That's a matter of personal preference I think. Also, if you don't first have a USMNT jersey with one of the guys on it I would start there. Begin with the basics and then expand to the cool off--beat stuff.
