Ozil expects to stay at Bremen
The 21-year-old has been linked with a move to the Spanish giants after turning down a new contract with the Bundesliga club, which means he will be available on a free transfer next summer.
However, Ozil does not expect any offer to tempt him away from Germany a year before his contract expires.
"I am really, really happy for Sami and I am keeping my fingers crossed for him," Ozil told the Bild am Sonntag newspaper. "It is very good for German football that big clubs are interested in German players. In recent years, there has only really been Michael Ballack who represented German football at a top club.
"For now, my situation for the next 12 months is clear. Only the facts count and the fact is, I am under contract with Werder. I cannot know what comes after that."
Ozil insists a move before the end of his contract will not happen unless Werder insist on selling him. He added: "I am a friend of honesty. Many people extend their contracts long-term for better conditions, but two weeks later, they want to leave.
"I have never done that but have rather always respected my contract and been happy to fulfil it. Why should now be any different?"
