The Djokovic fandom is escalating into paranoia.
Escalating? It has been there for quite some time now. This is just the latest example/confirmation.
Just the idea that people would be booing Djokovic after his opponent wins a point is completely insane. Why would Rune fans prefer to boo Djokovic rather that cheer for their own guy, after their own guy does something positive? It simply doesn't happen. Even in that Jarry v Moutet match in Chile, with one of the most hostile and unsporting crowds we have seen in quite a while, they cheered like crazy when Jarry won points.
That makes about as much sense as Medvedev's "small cat" comment.
Wait, is this sarcasm? I actually thought that was a pretty brilliant comment, especially for a non-native English speaker. Maybe something is lost in translation to other languages...
