He never made excuses for losses before. After every loss he would say "He just unbelievable player....he play much better than me today." Now, when the discussion is regarding Djokovic, Nadal has started becoming more and more like Federer with his excuses. He's pulling the injury card after every loss. In his last interview he brought up a pulled hamstring and heatstroke in two different losses. What happened to the whole "I accept losing with the same calm as the winning?" I'm fearing that if Djokovic himself hears some of the bitter excuses coming out of Nadal's mouth in these interviews lately, it's going to inspire Djokovic even more when they meet in the future.
