Novak Djokovic said his confidence was high after beating Kevin Anderson at Wimbledon, but that doesn't happen by accident.
Djokovic was in dominant mood on Centre Court as he easily won a re-run of the 2018 final 6-3, 6-3, 6-3.
He, though, says confidence comes from preparation as much as it does from winning, and that is why his is so meticulous away from the court.
"Obviously I'm in a high level of confidence after winning [Roland Garros]," Djokovic said.
"But I was nervous coming into this match because I was playing a very good player, experienced player, whom I faced in the final three years ago.
"He's a big server. He's very dangerous opponent, especially in the early rounds.
"But I've done things on and off the court to make myself feel that I'm focused, yet at the same time calm and composed and clear with my game plan and what I want to do. Obviously did my homework, talked with my coach, worked well on the practice court.
"I think it's a combination of all these factors that make you feel confident on the court and to execute the shots that you want."
