Wenger's men salvaged a 2-2 draw at Tottenham but fell eight points adrift of league leaders Leicester City, which enjoyed a 1-0 win at Watford.
This season appeared a huge chance for Arsenal to claim its first title since 2004, with a pair of FA Cup triumphs having bought Wenger some time, Omnisport reported.
Wenger said unhappiness from the club's supporters could be costly for his side, which is winless in three league matches.
"I prefer that the fans are happy," the Frenchman said.
"I'm more worried that it can get to the players' confidence level, but I feel we have shown a great response as a team that we can deal with that, we analyze that well.
"We gave the right response."
An Alexis Sanchez equalizer saw Arsenal earn a point in the north London derby despite playing most of the second half with 10 men.
Wenger said his team had the character to challenge, with their next league clash an encounter against West Brom on Saturday.
"You can feel sorry for yourself or respond straight away next game," he said.
"That’s why I think the group is healthy and there's a good mentality."
