The Gunners boss believes that without a healthy team spirit, the side cannot be successful this season.
The Gunners found themselves at a low ebb recently, with a highly demoralising loss to Olympiakos in the Champions League having left their hopes of qualifying hanging by a thread.
Morale has since been restored, though, with the north London outfit comfortably beating Manchester United 3-0 in a Premier League victory that will have their confidence soaring.
And Wenger says it is important to protect their current sky high spirit at all costs.
“How far can you go in cultivating and developing that team spirit?” he told arsenal.com.
“That’s our target. We know that to have a chance of being successful, we want to be more of a team than any other side in the Premier League. Therefore, I believe it’s a little bit like a flower. You have to take care of it.”
The Gunners were hotly tipped to be Premier League title challengers this season after a fine finish to the 2014/15 campaign saw them secure a second successive FA Cup triumph.
They have not started the season as quickly as many would have predicted, although last Sunday’s impressive win over Louis van Gaal’s side has left them second in the table, just two points adrift of leaders Manchester City.
If they are to be successful, team spirit will be key and Wenger says he believes you cannot win anything without it.
“Can you be successful without team spirit?” he added.
“It’s difficult to put a percentage on it, but you know without it you have no chance. You can have different degrees of team spirit, because without it you have no football at all - everybody would just do what he wants.”
