Chicago Fire suffered a minor setback in their opening match of the Simple Invitational on Portland on Sunday.
Frank Yallop's side drew 0-0 with Norway's Stabaek, managed by ex-USA boss Bob Bradley, in a lackluster affair in their pre-season tournament opener which provided an injury for new signing David Accam.
The Ghanaian striker, who recently linked up with his new teammates after joining the Fire from Swedish club Helsingborg, sustained a slight groin strain just after the hour-mark of the stalemate but his work prior to his forced substitution pleased his new boss.
"You could tell he's obviously a very, very good player," Yallop said. "Electric and all those things I've seen."
Regarding the overall showing of the Fire, a deflated Yallop added: "Obviously getting a clean sheet was good but I felt that for whatever reason we were very flat (in) the first half.
"The two other games we played I thought we moved the ball real sharply and crisply and played a lot better. We didn't play well today."
