Gunners fans backing the 'Black Scarf Movement' had demonstrated around the ground before kick-off, complaining at the perceived commercialisation of the club following their move to the Emirates Stadium, while jeers greeted the final whistle as Wenger's side dropped more points and fell down to 10th in the table.
Despite it being the worst start to a season under his tenure, the French coach insisted all was not lost.
He said: "We are in this job to turn things around, and I am confident we will [because of] the quality of the players and the spirit we have in the team. It is a good moment to stick together.
"I am not so much worried about [league] places, even if that is not the place you want to be, but I believe what is important is we get the quality of our game back. Then the places change."
Wenger turned 63 last month, but insisted there were no thoughts of calling time on his Arsenal career as he looks to guide the club back to winning ways.
"You make your assessment at the end of the season, as I said many times," the Arsenal boss stressed.
"I know that at the moment, you get some good news from everywhere because there is a lot of unrest everywhere.
"I believe it is a good opportunity to stick together and show we are a strong club."
