The Frenchman was pleased with his side's 1-1 draw with Manchester City and is refusing to give up on winning the Premier League title despite being seven points off the pace.
The Gunners suffered an alarming dip in form in late March, with a 6-0 defeat to Chelsea and a 2-2 draw with Swansea City causing them to drop down the table.
However, a spirited performance against Manuel Pellegrini's men at the Emirates, where they drew 1-1, pleased Wenger and he believes his side is now in a strong position heading into its clash with Everton on Sunday.
"We were a bit flat after the Swansea and Chelsea games, and what was vital for us was not to lose against City and if possible to win," he told Arsenal's official club website. "But at least [we had] to come out with a strong performance. We feel we have done that so I think we have turned the corner and we have an opportunity to show that against Everton.
"We have not given up on [the title] - as long as there is a mathematical chance we want to fight. It is disappointing to have dropped off top of course and we have to give absolutely everything to come back into it."
While the Arsenal boss admits that his club is not the favorite for the title, he says the team must continue to fight for the top spot.
"We’re certainly still outsiders. But if you don’t fight and you then have results like Crystal Palace v Chelsea [Palace won 1-0 at Selhurst Park] and you’ve given up because you didn’t believe, you would be absolutely 100 per cent guilty.
"We have a small percentage [of a chance] to do it, but with this small percentage you have to give absolutely everything to make it possible."
