The Cottagers travel to White Hart Lane knowing that they could climb out of the relegation zone this weekend, and Chadli believes that a good start for Spurs is imperative.
"It doesn't matter who we are playing, we have to have the right attitude and focus and it will be no different against Fulham this weekend," the Belgian told the club's official website. "We're at home and we want to win every game here.
"Hopefully we can make a sharp start to the game and not concede early like we have done in our last few matches. We've played very well at times in recent games, have created chances and scored quite a few goals as well, so if we can continue that on Saturday then I'm confident we can pick up three points."
Spurs are currently sixth in the Premier League.
