Yes. He is.
One guy plays out an entire five set match with a freaking virus (he had cold sores all over his face. He looked like he had the PLAGUE), and takes his loss like a man, without giving any excuses to cheapen it, while the OTHER guy gets his pussy ass kicked all over the court, only to give up due to 'general soreness' (WTF??).
Djokovic, either act like a man, or retire.
