Ozil has now entered the final 12 months of his contract at the Emirates Stadium, but has yet to pen a new one amid reports linking him with a move away.
Gunners boss Arsene Wenger remains cool about the situation, and just like with Alexis Sanchez, is willing to let Ozil run his contract down and leave for free rather than cash in.
That could mean Ozil will not get his wish of a move to the Nou Camp before the closure of the transfer window and will have to wait another 12 months.
Barca are being linked with a host of players after selling Neymar to Paris Saint-Germain, and Ozil is said to be one of them.
The Catalan giants have so far failed to lure Philippe Coutinho and Ousmane Dembele from Liverpool and Borussia Dortmund respectively, and it also remains to be seen if they can land Ozil.
