Wenger will have to embrace a new squad overseen by a different board whose policies may not align with those of Arsenal.
"He will miss the World Cup".
Arsenal will be targeting another strong performance against Leicester at the King Power Stadium on Wednesday, in what is Arsene Wenger's penultimate match as their manager.
Asked if he had received any offers, Wenger replied: "Yes, more than I expected!".
"If I was the new manager going into the club in the summer, the first thing I would say is: 'how much have I got to spend?'" Parlour said on talkSPORT.
Goal understands that former midfielder Mikel Arteta, who now coaches at Manchester City, and Juventus boss Massimiliano Allegri are the current frontrunners to replace Wenger. "I want to work well here until the last day of my contract and then (I will) rest a little bit and think about where I will go from there".
"But for sure I will be active". And I have a huge experience in management and the subtlety of people management. "I don't know how many illnesses he has had this season but the fella is not kidding me".
"I don't want to go any further on that into detail at the moment".
Speaking at a press conference earlier on Tuesday, outgoing Arsenal boss Arsene Wenger said Koscielny would be absent for six months after undergoing surgery.
Koscielny, capped over 50 times and a member of the France side that lost to Portugal in the Euro 2016 final, was carried off 12 minutes into Arsenal's Europa League semifinal second-leg defeat by Atletico Madrid last Thursday.
According to the Sun, some players in the Arsenal camp are unhappy with the amount of times Ozil, the highest paid player at the club, has ruled himself out this season.
"I will be like every Arsenal fan, I will wait until they've made a decision and then afterwards support the guy in doing well".
