Gareth Bale promises Wales will have "all guns blazing" in Belgium on Sunday evening.
Wales top their Euro 2016 Group B qualifying group after collecting seven points from their opening three games but face their biggest test so far in Brussels this weekend.
World Cup quarter-finalists Belgium are ranked fourth in the world and their star-studded squad operate in the best leagues throughout Europe.
Influential captain Vincent Kompany is out of the Wales game with a calf injury but Belgium will still be able to count on Chelsea pair Eden Hazard and Thibaut Courtois, as well as Everton striker Romelu Lukaku and precocious Manchester United winger Adnan Januzaj at the King Baudouin Stadium.
Belgium are big favourites not only to succeed on Sunday but also win the group, yet Real Madrid star Bale remains upbeat about Welsh chances in Brussels.
"We're in a great situation ourselves at the moment and we're looking forward to the game," Bale told FAW TV.
"We know how good a team Belgium are, but we also know how good a team we are.
"We're going to give it our all, go out all guns blazing and try and do as best we can."
"We know it's going to be difficult to go there and win but we'll be fully focused and fully prepared to do that and hopefully we'll come away with all three points."
Wales have traditionally been slow starters in previous campaigns but they have hit the ground running this time.
Bale scored twice in the 2-1 opening-day win in Andorra and he says they have embraced being on top of the group.
"It's something that I think we're all relishing, it's something that we're excited about," Bale said.
"Ultimately that's where we want to be and the fans have been amazing.
"It was important that we got off to a good start in Andorra and it's kind of been a snowball effect.
"The last two games at home the fans were incredible, ultimately I think they got us over the line in both games.
"Now we're top of the league, hopefully they will keep coming back and supporting us."
