Arsenal defender David Luiz insists their top four push remains alive.

Luiz believes Arsenal can still gatecrash the Premier League top four after victory over north London rivals Tottenham on Sunday.

The victory moved the Gunners four points behind their neighbours but still 10 points adrift of fourth-placed Chelsea – albeit with a game in hand.

"We have to try and continue in this way, try to improve," Luiz said when asked what the win does for Arsenal's top-four hopes.

“We are far (off), but we have a great team and we can continue in this way and try to win points every week."

Luiz also said of the win: "It is always a big game, a big derby with big history and everybody knows about this game.

“I think we did so, so well in the game – apart from the last 10 minutes where our team played with a lot of emotion and didn't use our brains to control the game and use one more player on the pitch.

“But that is part of these kinds of games and I am so happy because the team has an identity, we try to control the possession and score all the time but I think we just have to be more efficient up front.

“It is never easy to play against them but I am so happy with the performance of the team, because we really understood the game before it started, how we had to beat them and I think we did that on the pitch."
