Ange Postecoglou insists Tottenham must focus on themselves heading into the north London derby with Arsenal, rather than on denting their rivals' Premier League title hopes.

With four matches remaining, the Gunners are a point clear at the summit from reigning champions Manchester City, who still have a game in hand on Mikel Arteta's side in second place.

While Arsenal look to stay very much in the hunt for a first league crown in 20 years, fifth-place Tottenham will aim to reduce their six-point deficit to fourth-place Aston Villa, on whom they have two games in hand.

Spurs are winless in the last three north London derbies - winning just one of the most recent six - though they twice came from behind to earn a point in September's reverse fixture at the Emirates Stadium.

And Postecoglou has his sights firmly set on beating his side's rivals, and says his players are not driven by the prospect of thwarting their opponents' title bid.

"Not in terms of that as a motivation," he said when asked if he would like to dent Arsenal's title hopes.

"I understand the importance of winning against your traditional rival. I never believe your motivation should revolve around the demise of somebody else.

"Your motivation should be about yourself. We can win on Sunday, but it doesn't mean we are title contenders this year. I want to win because I want us to progress. I want us to be in a position fighting for the title.

"If that's your kind of measure, always peering over the back fence to see what your neighbour's building, you could both have the worst houses in the street because everyone else is building beautiful places, and you're looking over the back fence."
