Following the match, the official social media account of the Belgian team posted a graphic showing the final score with a direct caption: "Overturn this."
USMNT head coach Mauricio Pochettino addressed his uncertain professional future following the tournament exit.
"In the next weeks, we can start to talk if the federation wants to talk," Pochettino said.
Pochettino, whose contract concludes this summer, noted that formal evaluations would occur after a period of rest.
"Right now, it's about resting a little bit, to think, have conversations with the federation to see what the decision is.
I'm so happy.
We've built a very good relationship, now is not a moment to talk about (my future)," he said.
