Gibson's fighting message to wayward Tomic

Recently retired AFL star Josh Gibson has given Bernard Tomic a giant rev-up on reality television, but it appears to have fallen on deaf ears.

The three-time premiership winner, and two-time Best and Fairest winner at the Hawks told Tomic what he had to do to get his life back on track, after a series of backwards steps left the tennis player's career on a knife edge.

"I tell you what you need in your corner? You need someone who is going to keep you on track (mentally) and everywhere else in your life,” Gibson said.

"It’s going to start in here (in the jungle), it’s going to start with challenges, it’s going to start with doing s*** in the camp, it’s going to start with training with me.

“I’m going to push you, make you feel uncomfortable.”

Unfortunately for Gibson however, Tomic only had reasons not to follow the veteran advice, referencing his troubled childhood and his indifference to tennis.

"If I don’t want to do it, there’s no point in getting anyone (to help me), because I’ll go out and go party, do whatever," Tomic said.

Tomic also argued that the top players in tennis, such as Roger Federer and Rafael Nadal, make it impossible for him to be a superstar in his own right.

"I could’ve been top five, I could’ve won some Slams if I would’ve played back 10 years ago, I would’ve been top three in the world," Tomic said.

"But now in the last 10 years, you’ve got these three or four guys that control the sport ... there’s a lot of good players out there.

But Gibson was having none of the excuses, firing back with the attitude that made him one of the top players in the AFL.

"Exactly. Could have, would have, should have," Gibson said.

"They don’t have to (stop you from being a great tennis player).

"Who cares about the other players, I’m talking about you as a player.”

Gibson's attempt to mentor Tomic looks to be over as soon as it started however, with the wayward youngster reported to have quit the aptly named 'I'm A Celebrity, Get Me Outta Here' already.

Tomic was shaken after two rough challenges in the jungle, telling fellow contestants there was no point him being there anymore.

With an attitude like that, his 'Tomic the Tank Engine' nickname won't be going away any time soon.

Meanwhile, John Millman has produced a brilliant response to Tomic's suggestion that Australia can't win the Davis Cup without him.

Tomic, who has a 17-4 win-loss record in the Davis Cup, made the claim before departing for South Africa, where he is taking part in the reality TV show.

Millman says the Australian team is watching the program with keen interest and "supporting" Tomic to win it - but they are not supportive of his claim.

"Take it with a grain of salt. I don't think anyone got offended," Millman told reporters on Monday in Brisbane, where the five-man squad is preparing for their World Group First Round tie against Germany.

"Sometimes Bernie just says stuff.

"Everyone's entitled to an opinion and hopefully the boys can prove him wrong."

Tomic, who has dropped to a world ranking of No.168, expressed a desire to return to Davis Cup action once he sorts out his "problems" with Tennis Australia.

Millman said the 25-year-old would be a good addition to the national ranks if he can manage a return to full fitness and form, but pointed to last year's close shave in the semi-final against Belgium as evidence they didn't need him.

"I thought last year the boys were incredibly close," Millman said.

"Tennis is sometimes a game of extremely fine margins.

"I think we were a bit stiff not to get through.

"I do think you have to have a bit of luck and the rub of the green that goes your way.

"Obviously, Bernie in full form at 100 per cent is a great addition to any Davis Cup team.

"We'll see down the track if he gets there but in terms of can the Australian boys win it without Bernie? I'd say we can."
