In addition, there are also concerns over Ozil's physical robustness, with the ex-Wolfsburg man having missed 38 games across four-and-a-half seasons at Arsenal due to various fitness concerns. Both the players are less likely to sign a new contract.
The 29-year-old will be free to enter discussions with any club outside of England in January if his current contract, which runs until the end of this season, with the Gunners is not renewed.
Arsenal had even looked at the possibility of trying to sign the German sensation when the January transfer window opens.
Nacho Monreal told IBTimes UK: "Yes, the feeling is that they will continue".
And talks appear to have gone so well that they have discussed a January move to Spain so Schalke could at least collect some decent money for their player. It is hard to admit but the Catalan club are a much more appealing outfit than us and I reckon Ozil would snap their hands off. The situation is clear.
He played key roles in identifying players such as Robert Lewandowski, Ousmane Dembele and Shinji Kagawa for Dortmund in the past and Arsenal are expecting big things from Mislintat.
"So I could mention who I like but will they go after them, who knows".
It has been suggested for some time that the Germany global is reluctant to extend his stay at the Emirates Stadium, just one of three high-profile players, along with Alexis Sanchez and Jack Wilshere - who will be free to exit come the conclusion of this campaign.
The Gunners are now preparing for their Europa League trip to Cologne on Thursday night, before travelling to Burnley in the Premier League on Sunday afternoon.
