Chicago Fire are hoping they can build their playing roster and enhance the depth at the club.

Several Fire players from 2009 will not be around next season so the club has to work hard to strengthen a squad that was almost entirely used up last season because of injuries, suspension or transfers.

Technical director Frank Klopas says the main thing the club has to worry about at this stage was bringing in quality players to add depth to the playing list.

"The most important thing is the group," Klopas said. "The more that you can build a team and make it stronger and better and deeper (the better).

"The draft is very important," Klopas said. "You've got to be able to replace the crucial parts of the team. We need a forward, someone in the midfield and another solid guy in the back."

One player the Fire could pursue is Argentine forward Guillermo Barros Schelotto, currently of Columbus Crew, but facing some salary problems.

When asked of the potential of the 36-year old making his way to Toyota Park, Klopas tread lightly.

"Columbus still has his rights so I don't want to be saying anything too much," Klopas said. "I can only tell you that the guy's an experienced and good player. He's done very well in this league and for the Crew. But we don't have his rights so I'll just leave it at that."
