Peter Nowak, an assistant coach for the U.S. men's national team and head coach of the under-23 squad, has been named team manager of Philadelphia's new entry in Major League Soccer, the Union.

Nowak will serve as coach and general manager. The 44-year-old, who was not available for comment yesterday, will be introduced at a news conference this afternoon.

"For me, Peter was our No. 1 candidate from day one and we worked very hard to try to bring him to Philadelphia," said Nick Sakiewicz, the Union's chief executive officer and operating partner. "The mixture of his winning ways and personality fits the Philadelphia market perfectly."

A former captain of the Polish national team, Nowak won MLS titles as a player with the Chicago Fire in 1998 and as head coach of D.C. United in 2004.

Nowak had coached with U.S. Soccer since December 2006. He was Bob Bradley's top assistant and guided the under-23 national team to a 1-1-1 finish in the Beijing Olympics.

"I have thoroughly enjoyed working with him as both a player in Chicago and as a partner with the national team," Bradley said in a statement released yesterday.

The Union will begin play next year in a new, 18,500-seat waterfront stadium in Chester. According to Sakiewicz, the team already has sold more than 7,000 season tickets.

"Philadelphia is a great soccer community," Sakiewicz said.

He said that in addition to coaching, Nowak will be involved in all soccer operations. "I represent ownership, and Peter and I will work together," Sakiewicz said.

Nowak's aggressive, attacking approach to soccer was a major attraction for the Union, the team's CEO said.

"His style is to attack both sides of the ball, whether defending or attacking," Sakiewicz said. "That is the style we want to play and the brand we want to be known for."
