The French Under-21 internationals progressed through the ranks at Auxerre together before both moving to England in the summer.
But Younes will only be concentrating on getting the three points in the bag when the pair step out onto the field for their second meeting this season.
Our big defender said: “I haven’t been speaking to Bacary. I’ll speak with him after the game but not before.
“He’s a good player but their whole team is strong. However, we’re a very good team as well, so it’s a massive game.
“I just want a simple win in this game because it’s Arsenal and it’s a derby. The whole squad wants to move up the table, and I want to make this happen.”
