Chicago Fire midfielder Marco Pappa has signed a pre-contract agreement to join Dutch side SC Heerenveen in January.
Pappa, 24, joined Chicago from Municipal in 2008 and had attracted interest from a number of clubs in Europe, including Wigan Athletic, but has decided to continue his career in the Eredivisie.
Speaking to Heerenveen's official website, Guatamala international Pappa said: "I'm very excited about taking the next step in my career and signing with SC Heerenveen.
"The Fire gave me a great opportunity in 2008 and I am thankful to Fire owner Andrew Hauptman and Frank Klopas for the support and encouragement they have offered the past four years.
"I plan to do the club proud and put everything I have into the remaining matches with the Fire."
President of soccer operations Javier Leon voiced his support for the player's move and commended his professionalism.
"Marco is a great player and has been a big part of the club for the last four years," he said. "He is a true professional and has really developed as a player while with the Fire. We understand Marco's desire to play in Europe and fully support his move to Holland.
"It was key for us to keep Marco through the end of the season as we push for a spot in the MLS Cup Playoffs. We are grateful for his contributions to the club and believe Marco will represent the Fire well in Europe."
Pappa has signed a three-and-a-half year contract with Heerenveen, and will link up with his new club on January 1.
