The Arsenal star shot to fame playing for Germany at the 2010 World Cup.
And a host of top clubs wanted him after the tournament in South Africa finished.
Real Madrid eventually secured Ozil's services - handing over £12.8m to Werder Bremen.
But the playmaker has now revealed he was keen on a move to their arch-rivals Barcelona instead.
Ozil told Bild: "Arsenal were interested in signing me after the 2010 World Cup, as were Manchester United, Bayern Munich, Barcelona and Real Madrid.
"My agent sat down with Bayern to discuss a move. The club told him about their plans with me and how they intended to use me. He had similar talks with the other clubs that wanted me.
"Before I travelled to Barcelona, I was convinced that was my next club. I was leaning toward Barcelona. There was no team in the world that played more beautiful football.
"But Guardiola did not attend talks and he did not call me either the days after. He did not even send me a text.
What's hot
"He did now show me that he wanted to sign me as well. My interest in a move to Barcelona quickly decreased."
Ozil spent three years in Spain before moving to the Emirates in a £42.5m deal.
He'll be hoping to find form again when Arsenal face Liverpool tomorrow evening.
