Spurs are fifth in the Premier League after stuttering in recent weeks, but have games in hand on the teams above them.
The Iceland international wants a final push, especially after the disappointment of last season when Spurs finished fourth but lost their place in the Champions League to the competition winners Chelsea.
"All the players want to get there, especially because of last season," Sigurdsson said.
"It will attract more good players and hopefully keep other good players around.
"It's in our hands. Every game until the end of the season is going to be tough and very important for us."
Spurs' next game is against Manchester City this afternoon.
