Neither the Montreal Impact nor the Philadelphia Union have won since swapping forwards three weeks ago.
The Impact are also winless for the season but they have captured all three previous home meetings with the Union heading into Saturday's contest.
One of the league's biggest trades came April 4 when Montreal (0-4-3) sent Andrew Wenger to Philadelphia (1-2-5) in exchange for Jack McInerney, who led the Union with 12 goals in 2013.
Both forwards have scored once with their new clubs, with the Union going 0-1-3 since the deal and the Impact 0-1-2.
McInerney has insisted there is no bad blood for him regarding the trade while Wenger says he is looking forward to returning to Montreal.
"You always want to prove something whether it's how much worth you have in yourself and or in the way you perform," Wenger told the Union's official website. "It would be nice (to score), but I am also looking towards the rest of the season."
The pressure is greater on league-worst Montreal, which has allowed a MLS-high 14 goals. The Impact fell 4-0 at Sporting Kansas City last Saturday, resulting in first-year coach Frank Klopas and sporting director Nick De Santis both having to defend the direction of the club in the build-up to this match.
Montreal, one of four winless teams, has a MLS-worst minus-8 goal differential.
"The leaders and the rookies need to show fight and that's what's lacking right now," goalkeeper Troy Perkins said. "It's an issue of belief right now and we have to find that mentality that teams will have to work really, really hard to get points from us.
The mood isn't much better for the Union, who are 0-2-4 since a 1-0 victory over New England on March 15. Now Philadelphia will try for its first win at Montreal, where it has been outscored 9-4 in losing its previous three visits.
"Clearly this weekend's game is really important for us and really important for Montreal," Union coach John Hackworth said. "We think we have to change that, we have to go up there and be very confident about getting a result, continue the way we have been playing but we have to execute in front of goal better for sure."
Philadelphia failed to score for the first time in last Saturday's home draw with Houston.
Montreal has two draws and a loss at home but this will be its first home game outdoors on grass at Stade Saputo.
"It's the first time I think they've had the Saputo Stadium this year because they've played at Olympic Stadium because of weather," Union striker Sebastien Le Toux said. "It's a tough place to play because the fans are really behind the team and I think the players of Montreal really feel the support."
The Union could be hard-pressed to contain Impact forward Marco Di Vaio, who has five goals against them in five career meetings. Di Vaio's lone goal this season came in a 1-1 draw at Philadelphia on March 29, in which Wenger was sent off in his last game with Montreal.
