A goal by Jurgen Damm in the first minute of stoppage time was enough to push Atlanta United past Alajuelense 1-0 on Tuesday in the second leg of their Champions League series at Kennesaw State. It was Damm’s first goal for the club and was assisted by Ezequiel Barco.

With the win, Atlanta United advances to the quarterfinals of the Champions League for the third consecutive time. It will play the winner of the series between Philadelphia and Saprissa. The quarterfinals are scheduled to be played April 27-29 and May 4-6. Within MLS, Only the L.A. Galaxy have advanced to the quarterfinals of the tournament three consecutive years in its current iteration.

Despite playing a team that was missing seven starters from last week’s first leg, Atlanta United didn’t put its first shot on goal until the 53rd minute. It took 15 shots, putting five on goal.

“We have played one more game,” manager Gabriel Heinze said. “We have been fighting too. The most important is to keep working because we need to improve a lot of things.”

The goal was the result of a nice pass from Marcelino Moreno and a good run by Barco into space behind Alajuelense’ defense. After Barco ran onto the pass, he tried to round the goalkeeper. Because Barco pushed the ball wide, it rolled to Damm who had only to shoot it into an empty net.

“I know it was a late goal but it was good to score one so we continue adding those stats to our team and building off our performances,” Atlanta United fullback Brooks Lennon said.

The defense posted its second consecutive shutout, and that’s all it needed to do. It was helped by a kick save from Rocco Rios Novo in the 80th minute after a pass from an Alajuelense rolled past Anton Walkes.

Heinze’s lineup was composed of Josef Martinez as striker and captain in his first start since the knee injury sustained in last year’s league opener, Moreno and Barco on the wings, Emerson Hyndman, Franco Ibarra and Santiago Sosa in the midfield, with George Bello, Lennon, Miles Robinson and Walkes in the back four and Rios Novo in goal. The only changes from the previous game’s lineup were Martinez in place of Lisandro Lopez, Moreno in place of Jake Mulraney, and Rios Novo in place of Guzan, who was ineligible for selection because he received a red card last week.

Alajuelense was without six players, at least four of whom were starters, because the Costa Rican club failed to work with CONCACAF in a timely manner to secure visas, according to the federation. The club started only four players who started in the first game against Atlanta United.

Atlanta United’s best moments came in the final minutes of the first half. First, Robinson found Barco with a long diagonal pass down the left. Barco cut inside to shoot, but it was blocked out for a corner. On the ensuing play, Alajuelense’s goalkeeper came out to punch away the corner. Had he not, Robinson was there at the back post and unmarked. Then, Barco was fouled 20 yards from goal in the center of the pitch. His free kick hit the wall and bounced out for a corner.

Despite the effort, the Five Stripes finished the first half without putting any of its five shots on goal. It created just two chances, both by Robinson. But, more important for the team’s chances of advancing to the next round, Alajuelense also didn’t put a shot on goal.

“We controlled well in the first half against a team that was waiting in its own half,” Heinze said. “We need to be more patient when we have the ball.”

Heinze subbed Damm for Ibarra to start the second half. The move resulted in Damm moving to the right wing, Barco inside and Moreno to the left. As the team took the field for the second half, Heinze walked with Barco and could be seen talking to him over the 50 yards.

Heinze said he made the move because he wanted to get more offense in the triangle part of the formation on the right side of the field.

It began to work.

Atlanta United’s first shot on goal came from a blast by Moreno was pushed over the crossbar by Alajuelense goalkeeper Mauricio Vargas, one of the players forced to start because of the team’s visa issues.

Alajuelense attempted to answer two minutes later with a low, hard shot that went just wide of Rios Novo’s left post.

Martinez came out in the 65th minute and was replaced by Lisandro Lopez. Robinson became the team’s captain.

Moreno just missed scoring what would have been the winner in the 86th minute when his shot rolled wide.
