Operating costs at a 'substandard' venue are too high for the club to sustain and Garber insists that if DC want to continue in MLS they will have to depart to a more cost-effective home with the help of the league.
"We have to aggressively figure a solution out, and that solution needs to be figured out soon. And I am concerned about where this team will be in 2012," he said.
"I'm shocked to say that I believe they could be paying more for their lease in RFK than any other team we have in the league, and there is no doubt in my mind that it is a stadium that is substandard to what soccer fans are able to experience in many other markets in the United States and Canada.
"If that means that they can't get a new improved lease in DC, they've got to move to another facility in the region.
"I will be supportive of that, and in fact will help them do that."
