The Gunners' victory over Hull City saw them maintain a four-point lead over second-placed Chelsea, who won 4-3 at relegation battlers Sunderland, and moved further ahead of Manchester United, who lost at home to Everton.
Wenger, though, will not rule the champions out of the title race just yet.
"It is a surprising defeat [to Everton], but it is still early," Wenger said.
"We have seen that before, 12 points, only on us.
"We have just to keep winning to have a chance, and not worry too much about the others."
