Spurs are unbeaten in their last 12 matches ahead of their trip to Anfield to face Liverpool tomorrow.
The defender told the club's website: "It's important to win, the more you win the more you have confidence, that becomes spirit and that can change your mentality. Then, when you go on the pitch, you only have one solution and that's to win.
"It's a tough game, Anfield isn't an easy place to go and play. They also want to finish in the European places at the end of the season, so it's important for both teams. Arsenal don't play, so it's also a chance to go further ahead."
Tottenham are currently third in the Premier League table.
