Wenger has promised to reveal if he intends to stay "very soon", but after this excruciating afternoon he said finishing outside the Premier League's top four would have no bearing on his future. 'That means that they know, ' Wenger said tersely.
Many fans would think that, after such a awful result, that decision would be to leave the club.
Now in a lowly sixth place in the Premier League, pressure on Wenger to end his tenure as Arsenal boss has been steadily increasing but he now looks set to remain at the Emirates.
The issue is likely to split the opinion of fans, with renewed calls from some sections of the fanbase to end his 21-year stay at Arsenal at the end of the campaign following a 3-1 loss at West Brom. I have never seen anything like that from an Arsenal team and I hope Arsene Wenger went into that dressing room and told them what he thinks of them because that was not good enough today.
And when asked why he thought that, Pulis added: "Because he told me".
Under-fire Arsene Wenger seems poised to extend his managerial career at Arsenal, according to reports on Monday.
Arsenal made it clear in a statement earlier this month that Wenger would not be the sole decision maker when his future is considered at the end of this season, yet his desire to remain at the club would appear to put the owners in a hard position.
That decision would be in spite of the fans' protests during their defeat against West From on Saturday lunchtime.
A second plane was also hired to encourage trust in Wenger, but it all represents an undignified conclusion to the season.
But soon later a pro-Wenger message was displayed by another aircraft highlighting how divisive the issue has become.
With four defeats in five matches, Arsenal are on their worst Premier League run since the days of Stewart Houston's caretaker reign in the spring of 1995 and there is no guarantee of things improving after the worldwide break given Manchester City are their next opponents at the Emirates on 2 April.
Manager Tony Pulis said: "We are what we are and my players have done fantastically well to achieve the 40 points in the time that we've done it. We've worked on that but you have to have someone who wants to head it and you have to have the quality that comes in".
