Roger Federer is looking ahead to future success after winning Wimbledon for the fifth year in a row.
Despite holding 11 Grand Slam titles and a stranglehold on the number-one ranking, the Swiss champion is keen to add to his collection of honours.
Federer performed his latest heroics with a five-set win Sunday for a fifth straight Wimbledon title - beating Rafael Nadal for the second year in succession.
But there are fresh targets waiting for the 25-year-old.
"I haven't won Paris, Davis Cup, the Olympic Games, many other tournaments I'd like to win again," said the world-beater with 54 straight victories on grass, his last loss coming five years ago.
"But if I don't win them all, it's okay, too. I'm having a great run. I just want to enjoy tennis as well and not just put myself under pressure all the time. If I don't win, whatever, the Olympic Games, I won't be able to sleep the rest of my life ... that's not the way it is for me."
Federer expressed his joy at claiming his latest Wimbledon in front of Bjorn Borg, last man to win five on the trot.
"I'm just happy with such a great run, especially at Wimbledon, the most important of my life," Federer said. "I'm loving every moment of it, that's clear."
Federer now stands just three Grand Slam title short of the all- time mark held by Pete Sampras.
"Obviously, it's on my mind. Pete Sampras is maybe the greatest player we've ever had," said the man many now consider to hold that title.
"To come out and break his record, it's not the easiest thing, I know that. It takes me five Wimbledons and three Australian Opens and three US Opens to just get close to him. So it just shows you what a great player he was."
Federer said that he fells "mentally and physically still fit to go on for many more years to come."
He was tested Sunday for the first time over five sets in a Grand Slam final.
"That obviously alone is going to get emotions out of you because you're drained towards the end, you know, mentally and physically," Federer said.
"You fought your heart out, you know, the whole way. So in the end you want to come through as the winner because otherwise it's so disappointing because you came so close."
Even opponent Nadal cannot dispute Federer's fast pace through the record books.
"If the best player of history (Pete Sampras) has 14 titles, (Federer) has 11. So he's very close, and he's still playing unbelievable," said Nadal. "Anyway, if he wins 14 or 16 or 13, in my opinion, his tennis level is the best ever." dpa
