Aidy White predicts another close encounter with West Yorkshire rivals Huddersfield on Saturday but feels the Elland Road factor can tip the balance in Leeds' favour.
The club have launched a 'Paint It White' campaign this week in a bid to turn Elland Road into a sea of white for the derby clash, offering replica shirts for ?10 for all fans attending the game.
"It's a good deal for the fans and a good promotion to get everybody there in their white shirts," White told Press Association Sport.
"To look around the stadium on Saturday and see everyone there in white, it could be a fantastic sight and can only give the players an added lift."
White, who has found himself on the substitutes' bench in recent weeks following Stephen Warnock's arrival, insists a top-six finish is still within the club's graps despite three successive draws, but concedes Leeds will not have it all their own way on Saturday.
"It's not going to be an easy game at all," he added. "Local derbies are always harder, everybody's always up for the games, players and fans.
"I'm sure our's will get right behind us and we can go into the game full of confidence and belief.
"Our aim is three points. We need them to keep our push for the play-offs going.
"I'm sure we can get the three points and push on from there, but it will be tough."
Ardley took a chance on the 19-year-old Frenchman in January after he was released by Cardiff.
And Sainte-Luce put in a sparkling display on his full debut in Tuesday night's 3-1 win at Southend.
"Kevin Sainte-Luce started his first Football League game and we know what he is capable of with the things he can do on the ball, but he needs managing," said Ardley.
"He is still developing and he will have dips in form. But he is getting there fitness-wise and he can be a real handful for defenders."
