After weeks of tweets, rumors and reports the Seattle Sounders FC have officially loaned out forward Fredy Montero to Colombian side Millonarios.

On Monday, the club made it official, announcing that Montero, 25, will spend the 2013 season with the Bogata-based Millonarios.

It was also noted in the press release from the Sounders that the club has also signed him to a multi-year deal before loaning him out.

“Fredy has been a fantastic player and pro for Sounders FC over our first four years,” said Adrian Hanauer, Sounders owner and general manager, in a statement released by the club. “We wish Fredy the best of success with Millonarios as he continues to develop as a player. We hope this move helps Fredy’s chances of being called up to the Colombian national team, as he has certainly earned it.”

The move is a big one for Seattle as it will open up a Designated Players slot on the Sounders’ roster for the 2013 season. Currently Christian Tiffert and Mauro Rosales are taking up the other two slots.

Replacing the 25-year old forward will be a tall task though. Montero leaves the Seattle as the club’s all-time leading scorer with 47 goals in league play. In total, he has 60 goals and 43 assists across all competitions. Only Dwayne de Rosario has more combined goals and assists over the last few seasons than Montero does.
