Tottenham boss Harry Redknapp says the fans can have a major say in their top four bid.
Spurs face Bolton Wanderers this Saturday.
"The fans really made the difference against Arsenal and Chelsea and we need that again," Redknapp told the club's website. "The atmosphere in those two games was something special and the players can only be inspired by that.
"It will be a tough game as well. Bolton caused Chelsea all sorts of problems recently and then went and won at Stoke and we all know how hard it is to get anything at the Britannia.
"You can't underestimate how dangerous opponents Bolton are but we've been in fantastic form, seven wins in our last nine games and we've played some superb football at White Hart Lane this season, the fans must be delighted with what they've seen.
"Fourth place would cap it all and would be a great achievement.
"We all want to do it for the fans - and they can play their part as well against Bolton."
