In my opinion, Ozil shouldn't continue at Arsenal and should definitely leave as soon as possible.
@Swordsoffreedom this transfer makes sense for all the parties, because Arsenal are paying him huge salary just to sit outside the squad, and if he moves on then they can reinvest those funds to buy other player’s. Lastly do you’ll think that Ronaldo is convincing Juventus to get Ozil, because these two had played very well for Real Madrid?.
