USA vs. Sweden: What you need to know about the Women's World Cup showdown

A clash with former coach Pia Sundhage and perhaps some more playing time for Alex Morgan could be on tap for the U.S.

After opening the Women's World Cup with an imperfect 3-1 victory over Australia, the United States turns its attention to Sweden, expected to be its toughest challenge in group play.

Here's a rundown of what you need to know ahead of the match.

What, Where, When:

Group D game at Winnipeg Stadium

Friday, June 12, 8 p.m. ET, Fox

Mama Pia!: It won't have any bearing once the whistle blows and the game begins, but the talk heading into Friday's match will be all about Sweden's coach, Pia Sundhage. The 55-year-old has been on the job since 2012, taking over on the heels of a four-year stint in which she led the U.S. to a 91-6-10 record, a pair of Olympic gold medals, and a runner-up finish in the 2011 World Cup. Not known for her warm and fuzzy personality, Sundhage made waves this week when she said in a New York Times story she considered U.S. midfielder Carli Lloyd and goalkeeper Hope Solo a "challenge" to coach and added that all-time leading scorer Abby Wambach would be coming off the bench instead of starting if Sundhage were still in charge of the U.S. That could provide some extra motivation for the Americans on Friday as they gaze at the opposite bench.

More Megan: There's no doubt Megan Rapinoe is one of the more charismatic players on the U.S. team, but her performance in the opening game against Australia this week was a reminder of how big an impact she can make on the field. Consistently dangerous attacking down the left side, the midfielder scored twice in the World Cup opener and got the ball rolling on the other U.S. goal in the 3-1 win with a pass to Sydney Leroux, who set up Christen Press for what would prove to be the decisive tally. Rapinoe now has 31 goals and 32 assists in a USA uniform, becoming the first U.S. female player to reach 30 in both categories.

Desperation time: Sweden isn't in dire straits yet, as it will be favored in its final group game against Australia, but Sundhage and Co. weren't banking on coming out of their opener with a draw against Nigeria. That's exactly what the Swedes got, though, as their defense looked ragged and unable to sort out the Nigerian attack at times in Monday's 3-3 contest in Winnipeg. After taking a 2-0 lead in the first half, with one of those an own goal, Sweden gave up a pair to Nigeria in the first 10 minutes after the break. Sweden rallied to take the lead again but couldn't hold it, settling for the draw when Francisca Ordega scored in the 87th minute. Afterward, Sundhage said her team hadn't exactly followed instructions and said that had to change against the U.S.: "Next time, when we play the States, I hope we will follow the game plan."

Alex is back: Alex Morgan didn't make an impact coming off the bench in Monday's opener as she did in the 2011 World Cup, but the U.S. was just happy to see the forward back on the field. After missing two months with a bone bruise on her left knee, Morgan came on as a 79th-minute substitute against Australia and looked fine moving around and taking a few shots at goal. It was a no-pressure situation for the 25-year-old, designed to get her feet wet and timing back as much as anything. Now we'll see how much U.S. coach Jill Ellis wants to stretch her minutes as the tournament progresses.

Opponent to watch: Lotta Schellin was kept off the scoreboard against Nigeria but has been a prolific scorer for Sweden throughout her career. The 31-year-old has 80 goals in 151 international appearances and averages more than a goal a game for her club team, Olympique Lyon.

Up next: The U.S. plays its final Group D game Tuesday against Nigeria in Vancouver, with kickoff set for 8 p.m. ET.
