John McEnroe has warned Novak Djokovic he will have to face up to being the “bad guy” for the rest of his career after the world number one was defaulted from the US Open for striking a ball which hit a line-judge.

McEnroe, himself no stranger to grand slam defaults, accused Djokovic of making a “rookie mistake” after the incident, which saw the Serb tossed out of the tournament towards the end of his first set against Pablo Carreno Busta.
