The two teams are the only clubs to have won all three of their respective matches in the Premier League this season, and Fabianski believes that there is no need to fear one of the favourites for the title.
"It's a big game to enjoy, not to fear," the Polish goalkeeper told reporters. "Playing away at Chelsea is always difficult, but we don't have to be afraid of anyone.
"We went to Old Trafford and won on the opening day of the season so we know we can compete with the best teams.
"If we keep our discipline and takes our chances the way we have been then anything is possible."
Chelsea have been handed a boost in the build-up to the match with the news that Diego Costa could be fit enough to start in attack.
