According to the Liga Postobon official website, the 25-year-old Montero will be headed to the Colombian champion for the full year instead of six months as had initially been reported. Montero's father told Colombian radio station Blu Radio that the loan is for a year with an option to purchase and that the forward would be having a farewell dinner in Seattle on Tuesday before flying to Bogota to cement the deal.
Assuming the transaction is completed, Montero, who has scored 47 goals and assisted on 34 others in four seasons with the Sounders, will suit up for the side as it defends its domestic title and competes in the Copa Libertadores in a group with Mexican champion Tijuana, reigning FIFA Club World Cup champion Corinthians and Bolivian side San Jose.
Montero's pending departure leaves a massive void up top for the Sounders, who will turn even more to U.S. national team striker Eddie Johnson for production. His leaving would give the club financial flexibility, though, given his $600,000 base salary, according to MLS Players Union documents.
Should Seattle lose Montero for the year it would mark the second major defection from the starting lineup this offseason, with the club trading starting center back and U.S. national team January call-up Jeff Parke to the Philadelphia Union.
