MLS Commissioner Don Garber is confident that Major League Soccer can overcome anything.

With the league set to expand to 18 teams next season and the likelihood of heading to 20 by 2013, Garber says that any potential issues arising with such quick growth can be handled.

"We're still growing, but that's the exciting part of a new business," he says. "We'll overcome anything."

Portland Timbers and Vancouver Whitecaps enter MLS in 2011 with Montreal Impact following in 2012 and a potential 20th team mooted for the following year.
