The three of them have pretty good freedom to go where they want to go, but they also do a good job of balancing each other off, so that makes them a dangerous team because they’re very flexible in how they attack.” Sounders coach Sigi Schmid on SantosNEXT: The series resolves April 9 at Estadio Corona in Torreon.
