But the biggest problem for the Fire is the play on the field, which continued to be an issue on Sunday as the Fire managed only a 0-0 draw against the Colorado Rapids at Toyota Park.
Fire GM John Guppy has said that a permanent decision on the coaching search could be made this week. Guppy was not available to the media on Sunday, raising suspicion over recent rumors that the Fire is for sale.
MLS Commissioner Don Garber spoke with the media at halftime and addressed the rumors.
"It wouldn't surprise me if there was going to be a purchase of the Chicago Fire," he said. "I can't say anything more than that."
The Fire's defense had a solid outing thanks to the play of midfielder Diego Gutierrez. Goalkeeper Matt Pickens had one of his better games of the season with four key saves.
The offense was a different story as the Fire's passing was frequently off-target and provided few scoring opportunities.
The Fire's best scoring chance came in the 45th minute when Ivan Guerrero's cross found Willian Oliveira in the goal mouth. Oliveira one-timed the ball but saw his shot immediately scooped up by Rapids goalkeeper Bouna Coundoul.
"Tonight was disappointing," Hamlett said. "I thought the guys would be ready to play."
Midfielders Chris Armas and Thiago both came off the bench after missing games due to injuries. Guerrero, who was part of Honduras' Gold Cup team, returned to the starting lineup after missing the previous three games.
Former Fire goalkeeper Zach Thornton, who was traded to the Rapids during the off-season, did not play.
