The Serb expressed his hope that the injury was not serious and praised the Russian for being a "great guy, a fighter, and a big competitor.""I really hope that his injury is nothing too serious," Djokovic said, adding, "I know Daniil, he’s a great guy, he’s a fighter, he’s a big competitor. He wouldn’t retire a match if he didn’t feel that he [could] continue or [if it wouldn't] worsen his injury. He told me that he pulled an adductor muscle in his leg."The 35-year-old added that Medvedev played better in both sets than he did and expressed his sadness for the unexpected ending to a good match."It was such a close match, particularly in the second set. I would probably say he was a better player on the court in both sets. I was fighting and trying to find a way. I found a way to win the second, but I’m just sad for the tournament and for these people who were enjoying the battle, and for Daniil that it had to end this way," Novak Djokovic said.
