Spurs make the short trip to the Emirates Stadium later today with two wins from their first two matches of the season.
"Every point counts, so it's important to get a positive result," Sigurdsson told the club's official website.
"We know it's an important game for the club and the fans and it would be great to make it three out of three in the Premier League this season. It's a massive game for us."
Spurs were beaten 5-2 by their bitter rivals in the fixture last season.
