So, what exactly was that metal-looking object about the size of a bottle cap that was taped to Novak Djokovic's chest at the French Open?During the changeover between the end of the first set and the start of the second during the 22-time Grand Slam champion's 7-6 , 6-0, 6-3 victory over Marton Fucsovics at Roland Garros on Wednesday night, Djokovic removed his reddish polo shirt and swapped it for another.
"When I was a kid I liked Iron Man a lot, so I try to impersonate Iron Man," Djokovic said with a smile."My team delivers an incredibly efficient nanotechnology to help me deliver my best on the court, so that's the biggest secret of my career," Djokovic said sarcastically. "If it wasn't for that, I probably wouldn't be sitting here."Perhaps a sequel to this saga will come on Friday.
