They were beaten 4-1 by free-scoring Arsenal in their previous game and will now come up against a Chelsea side who have scored 20 goals in their last six games.
Chelsea have also not conceded a goal at Stamford Bridge in their last nine games.
While Wolves are massive underdogs to pull off a shock this weekend, Craddock still believes they are not facing an immediate return to the Championship this season.
He said: "We just need to keep playing our football.
"We've definitely got enough here, we've got a good bunch of
lads, and a young, hardworking team.
"We know it's not going to be easy - it's going to be tough,
but we've got enough here to see us through."
As for the challenge of tackling Chelsea, Craddock believes Wolves have to adopt a bold approach.
Craddock, who has scored three times in his last two appearances, said: "Anything can happen in a game of football -even when you play a top team.
"We'll be the underdogs and have got nothing to lose, so we might as well go there and go for it.
"This is the reason why we wanted to play in the Premier League to play against teams like this.
"Of course it's difficult but it's another good experience and we'll be going there ready to give it everything we've got.
"We showed for half an hour against Arsenal in our last game that we can play against the top teams when I thought we
"It's a matter of continuing that and making sure that if we do concede, we stay together, don't get disjointed and keep doing what we were doing before.
"But Chelsea are top of the league for a reason and we know we're going to have to grind things out."
Wolves manager Mick McCarthy accepts his team will be given no chance outside their own camp of causing an upset against Carlo Ancelotti's side.
He accepts their hopes of Premier League survival are going to depend more on how they perform in the two games
after facing Chelsea - against Birmingham and Bolton.
McCarthy said: "If we go to Chelsea and get something that would be brilliant.
"But it would be a real bonus because no-one thinks we'll get anything there.
"Our next two home games, Birmingham and Bolton, are the ones we have to win. They will be vital for us.
"It's alright saying we need to get our teeth into them, but there will be huge expectation and pressure on those games."
