UPDATE (Mar 21, 2013): The Chicago Red Stars confirmed the signing.

The Chicago Red Stars have signed German international players Sonja Fuss and Inka Grings and they are set to join the team on May 20th.

“Inka Grings has proven herself to be one of the most prolific scorers of the past decade,” said Chicago Red Stars Head Coach Rory Dames. “She brings an instant presence to our front line and has all the potential in the world to produce lots of goals for us. Like Inka, Sonja Fuss brings a wealth of experience at the international level. One of her greatest assets is her versatility and ability to play anywhere across the backline. She brings additional maturity we’ve been looking to add to our defensive core. We can’t wait for both of them to join the team.”

FC Zurich Frausen, Fuss and Grings current club, originally announced the news on their official website on March 17th. “The FCZ women wish Sonja and Incas all the very best for the new challenge, are grateful for what we have achieved” (via Google Translate).

Grings, third on Germany’s all-time career scoring with 64 international goals, scored 38 goals in 19 matches for FCR 2001 Duisburg during the 1999-2000 campaign. She then went on to eclipse that number at FC Zurich Frausen by scoring 32 goals in only 14 matches.

“I can’t wait to take on the new challenges,” Grings said. “Of course I’ve already done some research on the city of Chicago and the club. Being able to take the field with such amazing players will be a fantastic experience, and to compete in one of the world’s best leagues is simply the ultimate challenge. I believe any competitive athlete can relate to that. For as long as I play soccer, I will want to win, help the team perform at its best, and celebrate championships together.”

Fuss, a defender who previously played for women’s soccer powerhouse FFC Turbine Potsdam prior to signing with FC Zurich Frausen, was part of Germany’s 2003 and 2007 World Cup Championship teams as well as an Olympic bronze medalist in 2004.

“The NWSL will be considered one of the world’s strongest leagues,” Fuss said. “Being the competitive athlete I am, accepting that challenge was a no-brainer. I’m excited about my new team and especially about playing alongside Shannon Boxx, one of the world’s best midfielders. I’ve been to Chicago once before with the national team and now I can’t wait to explore the many other sides of this culture-rich city.”

Fuss and Grings would be the first German players to be signed to a NWSL team.
