Freedman's team are big underdogs in the third-round tie, but he believes that it is vital for his players to concentrate on their own games, rather than the strength of the opposition.
"The key is to respect Chelsea, but not be in awe of them," the Bolton boss told reporters.
"It's a bigger stage. I won't be losing any sleep about who Jose Mourinho will be picking - whatever team he picks it will be a strong side.
"As a player you need to big up yourself a little bit. That's part of it. You can't just think you're a man of the street as if you've never played before. We won't be in awe of them."
Bolton are without a win in their last 18 games against Chelsea.
