Defender Laurent Koscielny says youngsters Hector Bellerin and Francis Coquelin have become an important part of the Arsenal squad.
Bellerin, 19, has been in impressive form for the Gunners this season with 23-year-old Francis Coquelin stealing the headlines after his dominating performance against Manchester City away from home.
And Koscielny says the two should be given credit for Arsenal's recent run of positive results.
"I've known him [Francis Coquelin] for a long time and knew that he has the quality to play for Arsenal," the defender told Arsenal Player.
"Now he is ready in his head and you can see that he's played four or five games and he's very important because we are stronger in defence.
"He cuts out little balls in front of us and after he has the quality technically to give some good passes for players like Santi Cazorla, Mesut Ozil or Theo Walcott. Now he has an important role in the team like [Hector] Bellerin.
"Before, [Bellerin] played well but now you feel he is more confident and has more freedom - that's good for us. He helps a lot of the team to go forward and puts in a lot of crosses.
"It's important to have some new blood in the team and I think they have helped us get some good results.
"To have more confidence and freedom on the pitch, you need to play more games.
"They did well against Manchester City, Stoke City and also in the game against Aston Villa, so I think they are ready to give 100 per cent of their quality to the team.
"You don't need motivation when you play a derby. It's the most important game in your season for the fans and the club.
"We will be focused, we will try to win because we want to stay at the top of the table and winning against Tottenham is always a pleasure for us, the fans and for the club."
