In his new autobiography, Gunning for Greatness, Ozil explains how he saw himself as "a nobody", before meeting Mourinho.
"Yes that's what I'll give you," Mourinho said. "A very real opportunity. Train hard. Then play. Show me you want it and I'll have you in my team. If you want to get better, I'll make you better.
"Real Madrid isn't too big a move for you. Real Madrid is the only right move. Trust me. I'll turn you into a regular player. And then all the doors will be open to you. You'll be able to show the world what you're capable of. And, believe me, that's a huge amount."
That persuaded Ozil - "an ambitious boy with a feeling for magic passes" according to Mourinho - not only to join the Spanish giants, but also "swept all my doubts away."
