Watch: Novak Djokovic pays tribute to late Kobe Bryant

The 36-year-old Serbian wore a 'Mamba Forever' shirt with an image of him next to Bryant during the trophy presentation. The T-shirt's back had 24 written on it, indicating the jersey number worn by the Los Angeles Lakers icon during his NBA career. Djokovic said Bryant, who died in a helicopter crash three years ago, had helped him through some of the most challenging times of his career.
