Martz, whose two-year, $2 million contract expires after the 2011 season, reportedly was offered a one-year extension for the same $1 million annual salary but was upset it didn't include a raise.
"I have a representative in Bob LaMonte who's the best at what he does," he told the Chicago Sun-Times. "I just do whatever he tells me to.
"He doesn't tell me how to coach, and I don't tell him how to negotiate. But he knows how badly I want to be here, and I would like an extension. I don't worry about it. I'm sure it'll work out."
Martz cited working with Bears coach Lovie Smith as one reason why he wouldn't be inclined to go elsewhere.
"It (the 2010 season) was as much fun as I've had in coaching in many years, and the reason why is Lovie makes it fun," Martz said. "He's a terrific head coach. He provides great leadership, and he lets you do your job."
