About the Revolution: The Revolution's leading scorer is not a forward but a midfielder. Lee Nguyen, who has started all 19 games, tops the team with five goals. He also has seven assists this season. ... Forward Kei Kamara has made a strong first impression since he was traded from Columbus in May. In his last four MLS games, he scored three goals, which is not surprising considering he finished 2015 with 22 scores. . . . The Revolution entered Tuesday with the worst goal differential (minus-7) in MLS. . . . New England, which is in sixth place in the Eastern Conference, won the Open Cup in 2007.
