Mesut Ozil and Alexis Sanchez inspired an impressive derby win and Wenger believes it can be a crucial moment for the Gunners this season.
The pair are both out of contract next summer and have refused to sign huge offers worth £250,000-a-week and £300,000-a-week respectively.
But Wenger, with anger in his voice, believes days like Saturday’s win canconvince Sanchez and Ozil to help bring the glory days back to theGunners.
He said: “I know them well and I know that when these guys go on the football pitch they want to win the game.
“They’ve shown their commitment again; I’ve never questioned their commitment.
“I’m long enough in the job that I know that one game is not enough to make them sign. The quality of the contract has to be good and enough for them.
“Is it just the quality of the contract? No. It’s part of it. The whole thing has to be right.
“They have to be happy. They want to stay but as well other top clubs out there offer good contracts as well.
“But I am convinced they love the club, they love the team.”
Arsenal beat Spurs thanks to goals from Shkodran Mustafi and Alexis Sanchez.
Tottenham weren’t at the races and Harry Kane and Dele Alli were both subbed off in the second half after below par performances.
The result sees Arsenal pull within a point of Arsenal but remain in sixth after other results.
Tottenham dropped to fourth after Chelsea thrashed West Brom 4-0 and it was an uncharacteristically flat display from Mauricio Pochettino’s side.
Pochettino, though, was disappointed with the first goal after it came following a soft free kick.
He said: “I do not need to say anything. It was obvious for everyone here and watching at home. It is not easy to accept because we lost the game but we have to move on and keep going.
“The free-kick for the first goal and the first goal was obvious offside, maybe the second was too.
“When you play against a team in the top six, the big details are up to you. Sometimes things go against you but that is football.”
But Wenger insisted his side put in a performance worthy of the three points.
He said: “I am very proud of the performance of my team. We played with purpose, desire and urgency and looked dangerous with a great solidarity.
“Mustafi was outstanding, the back three were outstanding. We threw our bodies in front of shots and were good on crosses. It was a terrific performance from Ozil – he has shown he is not only a great football player but can work and play for the team. He worked hard defensively.
“All the front three were very good. It is difficult to single one individual out.
“We are very tight in the table. People want always to go quickly to different conclusions. Let us take the positives and transfer it to the next one.”
