That is according to a prediction made by spread betting firm Sporting Index, who have crunched the numbers following Arsenal’s 3-0 home defeat to Manchester City.
Wenger is under contract until the end of the 2018/19 season but could be forced out by the start of the summer.
Sporting Index’s model predicts that Wenger will leave on Monday, July 2 and spokesman Ed Fulton said: “Arsene Wenger has been under fire for some time now, but after watching his team throw away a chance at silverware last week, it appears his days at Arsenal are truly numbered.
“The exact quote is 122 days, suggesting Wenger will see out the end of the season but not much more than that, with the damage having already been done, regardless of whether the Gunners clinch the Europa League trophy.”
Wenger signed a new two-year deal last May after guiding Arsenal to FA Cup glory but a disappointing campaign has raised speculation over his future.
The Gunners sit sixth in the Premier League table but are 10 points behind north London rivals Tottenham, who currently occupy the final Champions League spot.
Arsenal suffered a 3-0 defeat to City in the Carabao Cup final on Sunday and lost to Pep Guardiola’s side by the same scoreline in the Premier League last night.
Bookies have slashed the odds on Wenger being the next Premier League boss to be sacked.
And Arsenal legend Thierry Henry has admitted it is painful to see Wenger’s empire crumble.
“The man has been more than magnificent for this club and everyone knows how magnificent he has been for me,” Henry told Sky Sports.
“So it pains me to see this situation, for the man.
“I was expecting a response today – some pride and passion. But it didn’t happen.
“I feel sad because this is the club that I love and a man I have a lot of respect for.
“You’re kind of lost for words. You get upset and you have a go but tonight…”
