Barcelona is still working to strength the team in the January transfer window.
Philippe Coutinho is a priority because of his age (25-year), qualities and creativity, but his transfer is not sure.
If Coutinho fails, then another player will go to Barça. The best alternative is Mesut Ozil, 29, currently playing for Arsenal.
The Catalan club already knows how much it has to pay for German services.
Ozil meets the conditions to play for Barça because he has a class, can play in the Champions League and can be sold in January.
However, there is a debate in Barcelona: there is no doubt about his class, but about his ability to sacrifice.
Mundo Deportivo has learned that the Catalan club has already made the move to understand what the German price would be, which many English media estimated to be 10 to 15 million euros.
According to information provided by Barcelona , Ozil may cost about 20m euros.
