Pochettino said soccer should remain separate from the geopolitical events.
"I think we can’t mix political things with sport," he said. "It’s not because I don’t want to talk. I have my ideas. But I represent the federation, and I (don’t) want to talk about politics."
Marsch declined to delve into the topic, but did concede that rising tensions could influence the fixture should both teams advance to the finale. The USMNT play Panama in the semifinals Thursday, with Canada taking on Mexico. The winners will meet for the trophy Sunday night.
"I’m not going to get political right now," Marsch said. "I think I’ve made my statements clear and known. I will say that I do think from watching the 4 Nations in hockey, you can see that the climate for sports in North America has been elevated for national teams.
"I’m really hopeful that this tournament can be the best reflections of our societies, in that we don’t have to waste time booing anthems and getting caught up in politics, and we can just focus on the players and the teams and supporting the love of the game, and then whatever your nationality is, that you can support your team all the way."
