Novak Djokovic has dismissed claims from his former coach that he is suffering from a number of "personal problems". His statistics have prompted his first coach, Jelena Gencic to question his mental state heading into the US Open due to personal issues, but Novak has shut the claims down saying, "I'm sure she didn't mean any harm. Everybody has problems. My problems are much smaller than an average person's problems. I cannot complain about my life."
