LONDON -- Jan Vertonghen has said he believes Arsenal's positive approach could lead to a change in fortune for Tottenham Hotspur in Sunday's North London derby at the Emirates Stadium.
Spurs are without a win in five matches, including draws in the Premier League against West Bromwich Albion, Bournemouth and Leicester City, and have scored just once from open play in that time.
Arsenal can open up a six-point gap on their rivals if they win on Sunday, but Vertonghen says the Gunners' attacking style could help the visitors.
"It will be a very intense game, with both teams playing very positive, attacking football and I'm looking forward to that game," he said after Saturday's 1-1 draw with Leicester at White Hart Lane.
"Normally we do well against teams like that. I think the teams we've played, like West Brom and Leicester, they play the same way -- they sit and they wait for a mistake.
"Bournemouth were very positive, though. I don't think they've played differently against us.
"I think we've just been unfortunate. We've had some chances and we were unlucky not to take them."
Vertonghen was inches away from his first goal for Spurs since March 2013 when he headed against the bar in the second half against the champions.
"We're probably unlucky in every game we play," the defender said. "I think we were the better team and we deserved to win, but we just can't win at the moment."
He praised Vincent Janssen, who gave Spurs the lead with his third penalty for the club but has yet to score in open play.
"I don't think he is short on confidence," he said. "He's a very confident striker. He knows his qualities and he will score goals.
"He's a very good penalty taker and he's scored all three of them. He's a striker and he wants to score. It's very good that he takes responsibility."
