Sigurdsson says Spurs go into the game in prime form after victory over Arsenal.
He told the club's website: “We've had a run of massive games and they keep coming,” said Gylfi. “We had Lyon, West Ham, Arsenal now Inter. It’s a special game.
“Inter have quality throughout the team and I’m sure it will be tough to break them down but the way we’ve been playing for the last few months, we want to attack and score goals, especially at home and aim to get a good result to take to the away leg.”
