Atlanta United’s Champions League schedule is set.

The Five Stripes will play at Alajuelense in Costa Rica at 8 p.m. April 6. It will mark Gabriel Heinze’s debut as the club’s manager, as well as the debuts of several new players and the possible return of Josef Martinez.

Atlanta United will host Alajuelense at 6 p.m. April 13 at Kennesaw State. The team has hosted several games in various tournaments at the 8,318-seat college stadium.

A team spokesman said the club is working with officials at Kennesaw State, CONCACAF and local health authorities to determine whether supporters will be allowed into the stands. The spokesman said they hope to have more information in coming weeks.

It will be Atlanta United’s third consecutive year competing in the Champions League. It was eliminated by Monterrey in the quarterfinals in 2019 and by Club America in the quarterfinals last year. It qualified for this year’s tournament by winning the 2019 U.S. Open Cup.

Atlanta United is scheduled to open its league season April 17. The league has yet to release the schedule. Training camp is scheduled to open March 3.

Should Atlanta United advance in the Champions League, it will play the winner of the series between Saprissa and Philadelphia in the quarterfinals. Those games are scheduled to be played between April 27-May 6.
