Gabriel headed home a 96th minute winner for the Gunners, though also clashed with Woltemade after the Germany striker had opened the scoring on the day.
He later said: "After the goal there was a situation I felt his elbow in my face in two metres, so his arm has to be really high. I don't know I just said it to the referee that I felt something in the face and I think it's not right to feel something in the face but I'm not the type of player to fall down for this. It's hard because sometimes maybe you have to do this but this is not my type of football.
"He said sorry after, so I think he knew he hit me in my face. I didn't solve the situation to be honest."
On why he didn't accept the apology, Woltemade added: "I don't like this, if you do some things in game and then a few seconds you say sorry, that's not part of the game.
"I like this situation where you can have a good battle but his elbow should not be in my face."
