With FC Dallas leading conceded goals so far this season with 14, head coach Schellas Hyndman is looking for answers.
"We continue to talk about it," said Hyndman.
"Concerns for the last four games have been that we're giving up a lot of goals, two goals a game on average.
"We've been able to address a lot of the goals that have been scored on us last year from the flanks. Now we're trying to address the number of goals that come through the middle.
"If you look at our last game against DC United, both goals came through the middle and the same player. So unanswered goals are very concerning but all we can do is continue addressing it."
