Ozil's former English teacher and mentor, Christian Krabbe has lifted the lid on his old pupil.
Speaking to the Daily Mail, Krabbe said: "Mesut is a grounded person. He paid for a class trip for his friends to London with his first salary at Schalke aged 17.
"He has funded other school trips to London since he joined Arsenal.
"We went to a Turkish restaurant in Golders Green, where Mesut wrote a card for each student and paid for everything."
