Holloway - whose side were beaten 6-0 at Arsenal last month - admits it will be difficult to judge exactly what standard Chelsea are at until the match gets under way on Sunday afternoon, but is adamant he will approach the task without fear.
Asked how good he thought Chelsea were, Holloway said: "I don't know, I haven't seen them yet - only on a tape. You only find out when you are on there against them.
"My lads will have to get a lot closer to them and a lot tighter to the ball, and not concede too much ground or make it 'races', because we lost them against Arsenal and we will probably lose them against Chelsea.
"We have got to get our shape right and get our balance right. Hopefully if they do get any chances, Gillo (goalkeeper Matthew Gilks) will be in the form he was in last week.
"I want them to enjoy the game - away at Chelsea, Stamford Bridge, the champions who are unbeaten for who knows how many matches at home. It is a fantastic club we're taking on.
"I'm respectful of everyone, but fearful of no-one."
