New York Red Bulls should open their CONCACAF Champions League campaign with a win, while America look for another victory.
Mike Petke's Red Bulls host El Salvadorian club FAS on Tuesday, looking to put pressure on Group Three leaders Montreal Impact.
The Impact have beaten FAS twice already in the group stages, and the Red Bulls would like to do likewise in their bid to finish top and reach the quarter-finals.
On Saturday, the Red Bulls claimed a 4-2 win over the Impact in MLS after braces from Thierry Henry and Bradley Wright-Phillips.
Henry said his team needed to perform in every game for the rest of the campaign as they eye a play-off place.
"We started well the first 20 minutes. It was typical first half, we weren't good enough," Henry said.
"They scored, then it became difficult because they have quality.
"It was a conference game. We needed to win. We needed to be strong at home. You have to almost win them all right now.
"It was a must-win game, like every game will be until the end of the season."
FAS pushed Montreal in both matches but went down 1-0 in Canada and 3-2 at home.
