What: Sporting Kansas City (9-3-2, 29 points) at Union (2-8-2, eight points)
When: Saturday, 7 p.m.
Where: PPL Park, Chester
Outlook: Union interim manager John Hackworth said the days of his club's having a primary goal-scorer are gone. Now he visualizes goals coming from a team effort. A prime example can be found in Sporting Kansas City, with four players with two or more goals. Led by Kei Kamara and C.J. Sapong (five goals each), Sporting are on a four-game unbeaten streak in MLS. . . . Graham Zusi has emerged as a playmaker for Kansas City, with a league-leading eight assists. . . . Sapong and Kamara also lead the club in game-winning goals (three). . . . Goalkeeper Jimmy Nielsen boasts a 0.79 goals against average with an MLS-high six shutouts. . . . Union midfielder Freddy Adu summed things up best: "Kansas City is possibly the best team in MLS right now, but we are going in with a a pretty effective game plan. If you ask me, we beat [D.C. United] in every category except the score sheet [losing, 1-0, last Saturday], and we grab a lot of confidence from that. We need to finish our chances, and if we do, we're going to make it very tough on Kansas City."
