The USMNT is reportedly set to enter a new era under Mauricio Pochettino, and Slonina may begin with a leg up. He has previously played under Pochettino, albeit briefly before Chelsea loaned him to Eupen last summer.
There's a familiarity there, and Slonina knows what to expect under the Argentinian manager.
"Camps are going to be tough for sure, because he's a guy that pushes his players to work off the field," Slonina said. "How you train is how you play, and I think that's the mindset he goes into it.
"He's a very tactical-minded coach, so I think it's going to be difficult to adapt to that and everything, but the players will take it on. There are class players with the U.S. men's national team. So it's going to be a change for sure, but one that we will be able to adapt to."
