A semi-finalist at SW19 in 2014, Dimitrov has suffered a slump in form over recent times and, even though he is only 25, arrived in London with question marks over whether or not he can live up to the promise that earned him the nickname 'Baby Federer'.
A straight-sets, 6-3 6-4 6-2 victory over Bjorn Fratangelo does not mean those questions are now answered, but it at least gave Dimitrov something to smile about after a run of six straight losses.
He still believes in himself, too, and had the confidence to ride out his claim that he is 'fearing no-one' when world number one Djokovic opened the door to his interview room and asked: 'Are you sure you're not?'
Laughing, Dimitrov said: 'No, especially you. Especially you.'
He added: 'Honestly I don't fear anyone. I have beaten top players and in big tournaments.
'I'm not afraid to get out there and get my hands dirty. I'm very happy to play right now.
'I know I have very tough rounds in general. I'm unseeded. It sucks, you know, I must say. It's been a while since I haven't been seeded.
Dimitrov was stationed out on Court 16 for the clash with Fratangelo and, although he would clearly have preferred to have been on a bigger court, he was not too concerned.
In fact, he hopes it can prove to be a good omen for him.
'It was definitely different,' said Dimitrov, who next meets Gilles Simon.
'I played my first round there as a junior before I won the tournament. So I took it as a good sign, to be honest.'
