Philadelphia fan favorite Sebastien Le Toux is coming back to the Union.

The MLS team re-acquired Le Toux in a trade with the New York Red Bulls for forward Josue Martinez and allocation money on Thursday.

"We are happy to welcome Sebastien back to the club," said Union team manager John Hackworth in a statement. "His determination and heart are a perfect fit for the mentality of this team."

The Union will hold a news conference today at 10 a.m. at PPL Park to formally re-introduce Le Toux.

Le Toux, 28, was originally acquired by the Union as the fourth overall pick from Seattle Sounders FC in the 2009 MLS Expansion Draft. In his first stint in Philadelphia, the Frenchman led the Unio in goals in back-to-back seasons.

In 62 appearances (28 in 2010; 34 in 2011), he is the Union's all-time leading scorer with 25 goals and 20 assists, and is the only player to net a playoff goal, having scored in the first leg of the 2011 MLS Eastern Conference semifinals against Houston.

Le Toux was traded from the Union to Vancouver on Jan. 31 for allocation money in a move that was extremely unpopular with fans. In 19 games with the Whitecaps, he had four goals and an assist. Then on July 13, Le Toux was traded to New York for Dane Richards and allocation money. In nine games with the Red Bulls, Le Toux had a goal and an assist.

"In our hearts, Sebastien has always been a Union player and his contributions on the field and in the community while he was in Philadelphia were invaluable. We are thrilled to welcome him back and look forward to having him rejoin the club," said CEO & operating partner Nick Sakiewicz in a statement.

Red Bulls sporting director Andy Roxburgh said Martinez is a young player with potential and the allocation money will provide financial flexibility for the team. The 22-year-old started six of 18 games last season and had one goal. He has 16 caps for Costa Rica and has scored two goals.
