No doubt as a result of tonight's match being United's third in nine days, Ben Olsen has made two changes to the line-up that started Wednesday night's 2-1 victory over Seattle. Zimbabwean striker Joseph Ngwenya will partner Charlie Davies up front, while Stephen King will make his first league start of 2011 as he replaces Clyde Simms in midfield.
