Leon Goretzka, 22, is only contracted to the Bundesliga club until next summer, meaning he will be available to pick up on a free.
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.
That's because the competition for places at the Camp Nou is far higher than at the Emirates, and Martin Keown thinks Ozil should think long and hard about any return to Spain.
Just as Coutinho's transfer presents problems for Barcelona, so does that of Ozil, with the column stating his financial demands are simply "unacceptable".
Jurgen Klopp reveals why Chelsea are weaker this season
"There was a lot of wind and it was not possible for the plane to land first time, but the second landing attempt was possible". We have to do this. "Today we had a good training session and we tried to prepare for the game against Liverpool ".
Ozil's eligibility to play in the Champions League is understood to be a major factor in Barcelona's desire to sign one of Europe's top creative talents.
Another option for Ozil would of course be a new deal with the Gunners, and his performance against Tottenham Hotspur certainly had fans talking - with the partnership between the German, Alexis Sanchez and Alexandre Lacazette a joy to watch for fans.
He said: "I know them well and I know when these guys go on the pitch they want to win the game and they have shown that commitment again today".
Which brings me on to the very leading question - Is Mesut Ozil worth that kind of weekly salary?
They claim the player's representatives have already met with Barca officials to discuss a possible move to La Liga. "I am convinced they love the club, they love the team".
