Atlanta United advanced by defeating New England 1-0 on Saturday at Mercedes-Benz Stadium. Philadelphia advanced Sunday by defeating the New York Red Bulls 4-3 in extra time in Chester, Pa.

The two teams met twice during the regular season. Atlanta United went 0-1-1 with a 1-1 draw at Mercedes-Benz Stadium on March 17. Philadelphia won 3-1 at Talen Energy Stadium on Aug. 31.

Jonathan Tannenwald (@thegoalkeeper), one of the finest soccer journalists in the country, answered five questions about the game:

Q: What is Alejandro Bedoya's status? If he can't play, who will fill in and what are their strengths and weaknesses?

A: Bedoya should be fine. He was cramping up on Sunday and was out of gas, but he's expected to play Thursday.

Q: What is Kacper Przybylko's status? If he can't play, who will fill in and what are their strengths and weaknesses?

A: As of Tuesday afternoon, Przybylko was still questionable. My sense is he'll be in Atlanta - we should find out officially Wednesday when the Union train there - but I don't know if he'll make the game-day roster.

If Przybylko can't play, I assume Sergio Santos will start as he did against New York. Santos has a big gas tank, speed and some power, but he's not a great finisher. The question from there is whether the Union play a 4-4-2 with Santos alongside Andrew Wooten (who has yet to score in his time in Philadelphia), or a 4-2-3-1 with Santos up top (presumably with Brenden Aaronson on the left and Fafa Picault on the right).

Q: Who is the wild card for Philadelphia in this game? Why?

A:  I think the wild card has to be Marco Fabián. I won't be surprised if he starts, and I won't be surprised if he comes off the bench. He could be a heck of a late sub, as he was against the Red Bulls, scoring the goal that delivered the Union's first-ever playoff win.
