The Gunners looked like missing out on next season's Champions League a few months ago but have rallied to take 23 points from their last 10 games and sit fifth in the standings with just two games to go.
The Emirates outfit are just two points behind north London rivals Tottenham and therefore maximum points from their final two games of the campaign will see them secure a top-four finish and relegate Spurs, who have played a game more, to the Europa League.
Defeat will not automatically mean they miss out on Europe's elite club competition, as victory in their final game coupled with a Spurs defeat would still see them leapfrog Andre Villas-Boas' side into fourth place.
But Wenger would rather leave nothing to chance and is glad that the Arsenal players can decide their own future with two wins from two games.
"Two months ago we had no chance to be where we are today so we can only be happy with what we have done," he said. "Two months ago our destiny was not in our hands.
"Today it is so we have done that very well, so now let's finish the job and continue to play like we did until now and take the points."
Punters looking to use a free bet might fancy Arsenal to beat Wigan and put themselves in pole position to finish in the top four.
