Chicago Bears quarterback Jay Cutler has insisted that he is feeling good about his offense ahead of the start of the 2013 season.

Cutler has had to learn the ins and outs of new coach Marc Trestman's system in pre-season, and he believes that things are going as well as can be expected at this point.

"I'm as comfortable as I could be up to this point," Cutler told the club's official website. "We're still learning things and still getting better each and every day.

"I don't think we'll be where we want to be for this game, but eventually we'll get there each and every week. We've just got to be good enough to beat the Bengals this week and hopefully we are."

The Bears take on the Cincinnati Bengals on Sunday.
