Mesut Ozil's current contract with Arsenal will expire in July 2018. Therefore, if the "Gunners" do not make a move to keep the German midfielder, Ozil can negotiate with any club he wants from January 1, 2018 - the time when the winter transfer window officially opens.
After Xavi's departure and the upcoming Iniesta, along with the inability of Ivan Rakitic to ensure his expertise at the highest level, Barcelona is actively looking for an "A-class" factor to fill this position. The target is Ozil because in terms of his ability to create and keep the rhythm of the game, not many players in the world can do better than Ozil when he is at his peak. Another factor that made Barca make this decision was that the 29-year-old midfielder was too familiar with the La Liga environment due to his long time spent with Real Madrid.
An Ozil representative said that his customer is not sure about his future but will not accept any offers with great goodwill. Against Barca, M.U, PSG and Fenerbahce were the teams that opened the deal for this midfielder. However, the salary of 330,000 pounds/week was a barrier that forced all four of the above names to give up. And this is also the biggest problem for Barcelona.
Barca has just signed a 4-year contract with Messi and paid El Puga 500,000 pounds/week. If they "huge" Ozil with a salary of 330,000 pounds/week, the Barca top flight will have a "difficulty breathing". However, money is a matter and expertise is another matter. The reason for Ozil's decline in form is not outside the case of his contract with Arsenal when the two sides have many inconsistent terms. Look at how Ozil organized Arsenal's midfield in the win over Tottenham last week to see what the real talent of this star is.
After the lack of Philippe Coutinho of Liverpool, now is the time for Barca to urgently buy a true conductor in the midfield area. From there, Messi - Suarez will have more free time in the upper line and ensure to focus all their efforts on scoring.
