What happened: Mauricio Pochettino took the sideline at Nu Stadium in Miami for the opening leg of the Nations League quarterfinals between Haiti and the United States. The fixture marks Pochettino's second-to-last match leading the national team before he formally assumes manager duties at Manchester United. While designated as a home match for Haiti, the contest is being staged in South Florida.

Why it matters: United agreed to a two-and-a-half-year deal with Pochettino, allowing him to finish this window with the national team before departing for England. His imminent exit forces U.S. Soccer into an unexpected coaching search just months after Pochettino committed to coach against Haiti.

What to watch: The two-legged quarterfinal series wraps up with the second leg, which will be Pochettino's final appearance managing the United States.
