During Serbia's turbulent 1990s, Novak Djokovic's family endured extreme financial difficulties to support his tennis aspirations.
His father had to borrow money from criminals due to the lack of funding from the Serbian tennis federation and unavailability of bank loans.
Witnessing the effects of war and economic hardship, young Djokovic understood the immense sacrifices his family made for his career.
This challenging upbringing instilled in him a deep sense of gratitude and determination to succeed in the face of adversity.
