Philadelphia Union will learn their opponent for the Audi 2021 MLS Cup Playoffs Eastern Conference Final on Tuesday night as the New England Revolution host New York City FC. Kick off from New England is set for 7:30 p.m. ET with coverage on FS1 and FOX Deportes.

The Union and its fans are on the edge of their seats as a win by NYCFC would see the Boys in Blue host the Eastern Conference Final at Subaru Park on Sunday, December 5th at 3 p.m. ET.

Should Philadelphia Union face off against the Revs it would set up another postseason clash and give the Union the shot at revenge they've been looking for since last season when the Revs ended the club's Supporters' Shield winning season in the Conference Semifinals. New England made it to the Conference Finals and carried that momentum into 2021 with a league-record 73 points in the regular season to win the 2021 Supporters' Shield. The Union and Revs squared off three times in the regular season with each match featuring a battle until the final whistle. The two sides battled to a 1-1 draw at Subaru Park on May 12th with a scoreless affair until the 85th minute when Teal Bunbury grabbed the lead but the Union battled back with a Kacper Przybylko equalizer three minutes later. In August, the Revs nabbed a 2-1 win with a penalty kick in the first half proving to the match winner. The final battle took place during the FIFA World Cup Qualifying window with a youthful Union lineup going to New England and fighting until the final whistle that went the Revs way by a 1-0 margin.

Philadelphia Union and New York City FC squared off three times which was capped off with a Decision Day clash that saw the Union secure the No. 2 seed in the East with a 1-1 draw at Yankee Stadium. The first matchup between the two sides took place in May at Subaru Park with NYCFC taking a 2-0 win against a 10-man Union squad after Brujo Martinez was sent off in the first half. In August the rivalry intensity continued with the Union taking a 1-0 win courtesy of an Alejandro Bedoya finish in the second half and the Union defense standing strong to shutout their Eastern Conference rivals.
