Wenger feels the way his squad responded through such times is testament to their character.
"It will be a great achievement if we manage to do it. I believe it would be reward for a group which has exceptional strength," Wenger told Arsenal Player.
"They have come through some difficult times, always recovered and always battled. Therefore I will be extremely delighted when we do it."
The French boss added: "There is even more uncertainty because fourth place is not this time necessarily in the Champions League.
"Let's make sure we finish third and win our game - that is the only answer we can give.
"To do that of course you need a full, committed performance from everybody.
"On that front I am quite sure we will get that from our players and then we will have a very good chance to do it."
