The first spot in the Scotiabank Concacaf Champions League will be handed out on Tuesday night as Philadelphia Union looks to advance past Atlanta United FC. Kick off from Subaru Park is set for 8 p.m. ET and will be broadcast on FS1 and TUDN.

The Boys in Blue have the upper hand at the midway point of the series with a resounding 3-0 road win last week at Atlanta United FC. Andre Blake showed why he's the reigning MLS Goalkeeper of the Year with six first-half stops to keep The Five Stripes at bay and in the second half the goals came. Kacper Przybylko continued his push for the tournament's Golden Boot with a brace and an assist to Anthony Fontana to put the club 90 minutes away from a historical accomplishment, a trip to the Concacaf Semis.

Both sides are looking to bounce back from losses in league play with the Union playing 75 minutes with 10 men before falling to New York City FC by a 2-0 margin while Atlanta United fell on the road 2-1 to New England Revolution. Union Head Coach Jim Curtin will be forced into a lineup change with starting defensive midfielder Jose "El Brujo" Martinez suspended due to yellow card accumulation. Meanwhile Atlanta United Head Coach Gabriel Heinze said following the home loss that he was pleased of the team's effort that generated 16 shots and seven on frame but expect more clinical finishing if they hope to pull off the comeback.

Philadelphia and Atlanta both had their eyes on Tuesday night's tilt as Union starters' Kacper Przybylko, Leon Flach and Kai Wagner each came on as second-half substitutes while ATL gave some first-half rest to Miles Robinson, Josef Martinez and Ezequiel Barco.
