Novak Djokovic has taken his shock disqualification from the US Open as a “big lesson” but admitted he cannot guarantee he will not do the same thing again.

The world number one spoke at a press conference in Rome for the first time since he was dramatically ejected from the year’s second grand slam for hitting a line judge in the throat with a ball struck in annoyance during his fourth-round clash with Pablo Carreno Busta.
