Look over there. Closer. On the other side of the room.

It's Nick Kyrgios slumped at the bar and he's drinking at the Last Chance Saloon.

The bartender should have cut the 22-year-old off a long time ago but his patron is simply too charismatic.

After a tumultuous few hours listening to Kyrgios tell him he doesn't love tennis, it's too hard, he's not motivated, the public are too harsh on him... the barman pulls him in close for some free advice.

"Nick mate, you've got one more chance to win back the heart of a nation - bring home the Davis Cup."

Kyrgios and Bernard Tomic have polarised the Australian public like no other sportsman in this country, but only one still has a slither of support.

The public have completely given up on Tomic, a guy who open admits he'd rather take a pay day at some nothing tournament than represent his country.

Kyrgios has eaten away at a significant portion of his once vast fan base and the Canberran's last shred of support is hinged on his dedication to the green and gold.

The bloke might consistently embarrass Australia with his childish and inappropriate behaviour but at least he turns up and bleeds for the country.

Kyrgios' rollercoaster grand clam season ground to a halt this week and how many Australians get back on board next year will likely depend on his Davis Cup performance in the coming months.

With more slammed rackets than slam wins this year the keen observers will note the high points on this rollercoaster arrived in-between his brief appearances at the majors.

Kyrgios has been red-hot at times, beating Novak Djokovic twice in as many weeks en route to the Indian Wells quarters and was only denied a spot in the Miami Open decider after falling to Roger Federer in arguably the best match of the year.

Just two weeks ago he demolished newly crowned world No.1 Rafael Nadal in Cincinnati, as well as former world No.3 David Ferrer and current world No.13 David Goffin.

It's been a different story at the majors.

Kyrgios exited in the second round at the Australian and French Opens, before crashing out against lowly opposition at Wimbledon and the US Open where he fell to compatriot John Millman on Wednesday.

"I have had a diabolical year at these slams. It doesn't surprise me," Kyrgios said.

"It's just the story of my career, really. I will have good weeks. I'll have had weeks. It's just a rollercoaster."

After almost three years on the rollercoaster most Australians have motion sickness and are ready to get off for good.

But hold the phone.

If there's anything the Australian public will forgive above all else - it's a winner - and Kyrgios has the opportunity to deliver a win this country hasn't seen in 14 years.

Australia has been in the Davis Cup wilderness since Pat Rafter, Lleyton Hewitt and Mark Philippoussis downed Span in 2004.

Kyrgios has single-handedly carried the Aussies to the semis this year where they face Belgium on September 15 for a spot in the decider against France or Serbia.

"I have put a lot of effort into Davis Cup this year. I made myself available for every tie, really bought in, really gave everything. It is my goal to win the Davis Cup," Kyrgios said.

It's almost written in the stars - Kyrgios takes Australia through to the final where they meet Serbia and it all comes down to a fifth rubber against Djokovic.

Kyrgios takes down one of the greatest players of all time in a five-set thriller and wins back the heart of a nation.

Either that or he'll be turfed out of the Last Chance Saloon and head to where Tomic is drinking.

To borrow a line from Billy Joel - they'll be sharing a drink called loneliness, but it's better than drinking alone.
