Earlier this week, ABC, a Spanish newspaper with ties to the Spanish club's president, Florentino Perez, reported that the Blancos chief believed Ozil "wasn't a good professional and was obsessed with women and nightlife".
But the Germany international's father has hit back at those allegations and says the discontent which has greeted the 24-year-old's sale has seen Perez turn the new Arsenal signing into a scapegoat.
"Just because a man earns a lot of money, doesn't mean he's a man of honour," Ozil's father is quoted as saying in Bild. "And Perez is no man of honour.
"Mesut is supposed to be the scapegoat now and I'm the greedy father. A put-up game. We will defend ourselves legally.
"If Mesut had an unprofessional life in Madrid, then why did he always play? They want to blame him now, because the fans and team-mates are angry."
