The 20-year-old Spaniard feels Emirates Stadium is the right place for him to be now, having once again rejected the overtures from Real Madrid this summer.
Fabregas was quoted in the Spanish media as admitting he spoke to Real's president Ramon Calderon and sport director Predrag Mijatovic about their interest, but decided to remain at Arsenal.
However, Wenger insisted: "I did not allow Fabregas to talk to anybody. He denies he did.
"His agent might have spoken to Real Madrid.
"But Real Madrid are not entitled to do it without our permission.
"You expect other clubs to behave in a fair way when you have players under contract."
