Australian Open 2018, men's final preview: Roger Federer eyes 20th Grand Slam title against Marin Cilic
Cilic beat Federer on the way to winning the 2014 US Open final, but it is his only win in nine encounters and the defending champion has glided to the brink of another title without dropping a set.
Melbourne: Only Marin Cilic stands between Roger Federer and a 20th Grand Slam title as an injury-ravaged Australian Open staggers to its Sunday final at Melbourne Park.
The 36-year-old Swiss marvel continues to defy the years and attrition rate to reach his 30th Grand Slam decider and a shot at his sixth Australian crown while his long-time rivals have fallen by the wayside.
World No 1 Rafael Nadal, six-time champion Novak Djokovic and former winner Stan Wawrinka succumbed to injuries, while five-time finalist Andy Murray didn't even get to the starting line.
Yet Federer is again still standing.
Cilic overcame him on the way to winning the 2014 US Open final, but it is his only win in nine encounters and the Swiss defending champion has glided to the brink of another title without dropping a set.
Federer is supremely confident he has it all in place to join Djokovic and Australian Roy Emerson with the most Australian titles.
"It's not about having to improve anything in particular," he said ahead of the final.
"I'm pleased that my game has been good from the very beginning of the tournament so far.
"I mean, I've won all my matches without dropping a set. Things must be all right if I haven't dropped a set and in the final."
Federer was waved through to the final with an all-too-brief semi-final that lasted just 62 minutes when South Korean youngster Hyeon Chung retired with severe foot blisters.
Five of Federer's six matches have finished on or under two hours and he has been on court for a total of 10hr 50min, some 6hr 13mins less than Cilic.
"I would have preferred a normal end (to the Chung match), yes. But I must admit, as well, you do take the faster matches whenever you can," said Federer.
"There's enough wear and tear on the body, there are enough tough matches throughout the season that when they happen, you take them."
But he knows he faces a tough seasoned opponent in Cilic to win the big one.
"I definitely think him winning the US Open has given him great belief he can do it. If the big moments come about, that he can attain this level," Federer said.
"I like his attitude. He's very professional. He's always very much the same regardless of whether he wins or loses.
"On the court, he's a winner. He's there to win and not just to be there. I think he strives for more."
Win or lose Federer will remain World No 2 behind Nadal while Cilic is ensured of climbing from his current six to a career-high three.
Cilic, 29, has had a trailblazing tournament and is the first Croatian man or woman to appear in a Melbourne final.
His career high point so far has been the victory at the 2014 US Open where, as the 14th seed, he swept past Federer in straight sets on the way to beating Kei Nishikori in the final.
But he was in tears when he gamely played on with a nasty blister on his left foot in last year's Wimbledon decider against Federer, describing it as very tough to deal with.
Another opportunity to win a second Grand Slam quickly materialised when he toppled injured Nadal in the quarter-finals and rising British star Kyle Edmund in the semis.
He says he is in a good space with his serve and forehand.
"I'm feeling really good physically, even though I had a few matches that went more than three hours," Cilic said.
"I've played a great tournament so far, I'm playing much more aggressive, hitting most of the shots really good.
"From the return, moving, forehand, backhand, serving, I think everything is in a good, solid spot. Feeling really excited about the final."
But on facing Federer, he added: "When it gets to the semi-finals, finals, he gets better and better and is playing great tennis. So with him, it's always a big challenge."
On Sunday, Djokovic again felt the full, raw power of Nadal on clay as the Spaniard clinched a 10th Italian Open title with a 7-5, 1-6, 6-3 win in the final.

Playing his 500th clay-court match, Nadal staved off break points in the fourth game of the first set and did not look back to win through in 1hr 32min.
Second seed Nadal won through 7-5, 1-6, 6-3 in 2hr 49min against the defending champion in the 57th career showdown between the pair.
