DENVER: Emma Hayes got her international coaching career off to a flying start on Saturday as the United States defeated South Korea 4-0 in a friendly in Colorado.

Mallory Swanson and Tierna Davidson scored two goals apiece to give Hayes a resounding victory in her first game in charge of the American women since her appointment was announced in November last year. The 47-year-old former Chelsea boss was named to the US job in the wake of the USA's early exit at last year's Women's World Cup, and has been tasked with reviving the fortunes of the four-time world champions.

Hayes couldn't have hoped for a smoother start to her reign as a confident US line-up dismantled the Koreans in bright sunshine at a packed Dick's Sporting Goods Park in suburban Denver. "We were controlled in what we did in the first half, we struck to the structures and the coaching," Hayes said. "Everybody did what I asked of them. "It's really nice to feel like I've got the trust and the belief in the group to be able to play football. And while the American DNA and mentality is one that we don't want to lose, being able to play the way that we are is really exciting."
