London - Bernard Tomic admitted Tuesday he had lost all motivation for tennis and couldn't care less if he won or lost as every single Australian crashed out of Wimbledon men's first round.
The talented Tomic was once mooted as a rising star of the sport but says he has hit a mental block, facing another decade drifting around the tour earning money but with little chance of breaking the big four's stranglehold on the major prizes.
"Holding a trophy or doing well, it doesn't satisfy me anymore. It's not there," the 24-year-old said after being dumped out by Germany's Mischa Zverev, as all seven Australian men flopped at the first hurdle.
"I wasn't mentally and physically there with my mental state to perform. I felt a little bit bored out there.
"I couldn't care less if I make a fourth-round US Open or I lose first round. To me, everything is the same. I'm going to play another 10 years, and I know after my career I won't have to work again.
"You have to respect the sport. But I think I don't respect it enough.
"It's my choice. I know I have to work hard. For sure I don't do the right work."
Tomic reached the Wimbledon quarter-finals in 2011 and is the Australian number two behind Nick Kyrgios -- another troubled character.
But his world ranking has slumped from a career high of 17 last year down to 59.
"I just can't seem to find the commitment to work hard, to enjoy, and to lift trophies," he admitted.
"I'm just not super pleased, not happy with myself.
"I'm still 24, and it's tough to find motivation."
Tomic accepted he could shake up his support team in a bid to get his career going again but said: "I don't think I really want it".
Tomic's 6-4, 6-3, 6-4 defeat to 27th seed Zverev was all over in an hour and 24 minutes.
"I don't know what was wrong with him but I could definitely tell he was not 100 percent," said Zverev.
"Between points he was walking slowly, and he definitely acted like something was wrong."
It added to a played seven, lost seven wipeout of Australia's men at Wimbledon.
