Novak Rossonero: Djokovic holds a Milan shirt as he celebrates his US Open title

Footage has emerged online of the US Open champion and one of the best athletes in the world at the moment, Novak Djokovic, holding an AC Milan shirt while posing for pictures with his trophy at the Arthur Ashe Stadium in New York.

The all-time leader in men's Grand Slam titles (24 of them, to be precise), who has previously expressed his support for Milan, held up the black and red shirt to display the no. 24, recognising his most recent Grand Slam title, along with his nickname 'Nole' on the back.

Djokovic had been spotted at San Siro for the first leg of the Champions League semi-final between Milan and rivals Inter in May, and the two sides meet again on Saturday in the Derbi della Madonnina.

Giroud probably off, Rossonerri must transform for Derby della Madonnina

The tennis star had also said in an interview in 2014:

"My father was a professional footballer, and at home, we always watch the Rossoneri's games with great interest."
