The world number one and top seed eased to a 6-4, 6-4, 6 -4 win over Germany's Philipp Kohlschreiber on Centre Court but many eyes were glued to the Serb's coach Boris Becker after the German legend admitted he employed ways to instruct his player even though coaching is banned during a match.
Djokovic had spent large parts of the weekend defending Becker, a three-time Wimbledon winner, but admitted that many coaches use subtle means to encourage their players.
"I mean, are you asking only me or are you asking other players, as well?"
The usually affable Djokovic added: "I'm going to say that there are certain ways of communication which is encouragement, which is support, which is understanding the moment when to, you know, clap or say something that can lift my energy up, that can kind of motivate me to play a certain point. But it's all within the rules."
He refused to divulge if the German's means of encouraging him were in use on Monday where the Serb opened the two-week tournament.
