Arsenal exit for Ozil could be 'best solution', says Arteta
Despite reportedly being the highest earner at the club, Ozil has not featured since a 1-0 win over West Ham on March 7.
The 32-year-old has only six months left on his contract and is now free to talk to other clubs over a pre-contract agreement for next season.
However, he could bring to an end his eight-year stay in London in the coming weeks, with reports in Turkey saying Ozil is close to agreeing a deal with Fenerbahce.
"We will discuss internally what the best situation for him is for the near future, obviously with the player and the agent too, and try to find the best solution for everyone," said Arteta on Thursday.
"If something was sorted this month, it's because it is good for both parties, it is good for Mesut and his future, and it's good for the club. If that's the case, we will move forward. If it's not the case the player will stay here."
Clubs can make changes to those squads after the January transfer window, but Arteta hinted he is not likely to change his mind on Ozil's exclusion even if he remains at the Emirates for another six months.
"We know that we have a really important player who is one of the key players in the past few seasons for this football club," added Arteta, who played alongside Ozil for three seasons at Arsenal before retiring in 2016.
"We have to make a decision. I had to make a decision and I made it. I knew the consequences of it and now we're going to have to make another one in January.
"We will just (be) putting the balance on what is the best thing for the club and the best thing for the team, and what the intentions of the player are, and we will try to find the right solutions for that."
Arteta also confirmed that 19-year-old defender Omar Rekik is close to joining the club from Hertha Berlin.
