The Seattle Sounders have a chance to make MLS history when they face Sporting Kansas City on Sunday. The team has yet to concede a goal at home this season, a string of five consecutive shutouts, and could tie the Columbus Crew’s record of six home matches without conceding a goal. However, with several key players missing, including defender Nouhou and winger Cristian Roldan, the Sounders' defense is more vulnerable than usual. Sporting Kansas City has yet to win a game this season, but the Sounders cannot afford to underestimate them. Midfielder Albert Rusnak warned against complacency: "It's dangerous...sometimes when you play freely, you can be very good. I'm expecting a very tough game." To cover the gaps, the Sounders are likely to call up Cody Baker or Reed Baker-Whiting to the defensive line, and midfielder Obed Vargas will partner with Rusnak. Despite the challenges, the Sounders will be determined to put on another strong defensive performance to secure a new record and further strengthen their position at the top of the Western Conference.
