Union on the road: 0-2-2; Impact at home: 0-1-2.

Goals for: Union 9; Impact 6.

Goals against: Union 10; Impact 14.

Outlook: Both teams go into this match desperate. The Union have not won a game in more than a month, and the Impact are one of two winless teams in the Eastern Conference. Despite the Impact's poor start, this will not be an easy three points. Stade Saputo has historically been a tough venue for the Union. They are 0-3 there, including a pair of losses last season. . . . While much attention will be focused on forwards Andrew Wenger and Jack McInerney, who were traded for each other early this month, the Union cannot lose track of Marco Di Vaio. The Impact striker has five goals against the Union, including a hat trick last season. ... The Union do not have any key injuries. ... Manager John Hackworth clarified this week that Aaron Wheeler is his preferred choice at center back. Austin Berry, acquired in a trade over the summer, began the season as the starter. He injured his hamstring in the opener and had a rough outing when he returned against Real Salt Lake.
