Mathieu Flamini has stressed that Arsenal must not drop any more points if they are to win the Premier League title.
The Gunners take on Tottenham in Sunday's north London derby as they look to claw their way back into contention.
Flamini made his second debut for the Club in the hard-fought victory over Spurs in September and feels a league double over their closest rivals would be a "great achievement".
It's an important game because we feel the pressure, we know it's a derbyMathieu Flamini
"In the title race it's very important not to drop any more points because it's not a marathon anymore, it's a sprint," Flamini said. "We have a few more games and we want to win every single one. It's important we come back with the three points on Sunday.
"It's important now to focus on Tottenham and not to look at the other games because it's a sprint. We have a few more games to come which are not easy because Chelsea and Manchester City are also fighting for the title.
"But if we focus on Tottenham, play our football and win the challenges, it will be a great achievement for us and then we'll have time to think about the other games.
"It's an important game because we feel the pressure, we know it's a derby, it's important for the Club, for the players and especially for the fans. It's the kind of game you definitely want to win.
“It's like a huge emotion when you have the opportunity to win, so we'll do everything to win this game."
