Andy Murray was relieved to finally get his first ever Grand Slam win over Roger Federer at the Australian Open.
The Briton made it through to his third Melbourne final in four years with a dramatic 6-4 6-7 (5-7) 6-3 6-7 (2-7) 6-2 win over the four-time champion.
He will face Novak Djokovic in the final on Sunday in a repeat of last year's US Open final, when Murray won his first major title.
The Scot, 25, had previously lost to Federer in the finals of the 2008 US Open and 2012 Wimbledon, as well as Djokovic at the 2011 Australian Open.
"It's satisfying, obviously," said the Scot. "I've lost some tough matches against [Federer] in Slams. So to win one, especially the way that it went, was obviously nice.
"I'm sure both of us will play each other again in Slams, so it will help having won once against him."
Murray led throughout Friday's semi-final but was twice pegged back by Federer in tie-breaks, forcing a fifth set that had looked unlikely when the Briton dominated the early stages.
"I thought I did a good job," he said. "I think I did all the things I needed to do. I did them well. Even after the second and fourth sets, which were tough to lose, because I wasn't comfortable, but I was in good positions in both sets.
"To lose them was tough. I was just happy with the way I responded after both those sets."
Murray insisted that he had not panicked as the decider loomed, gathering himself for a final push.
"I was playing well," said Murray.
"After the fourth set he went and took a toilet break and I had a bit more time to sort of think. I'd put myself in a winning position and just had to think to myself what I'd done to get in that position and make sure I did it at the beginning of the fifth set."
Both men played down an apparent cross word when Murray first served for the match at 6-5 in the fourth set, the Scot moving to within two points of victory before Federer hit back to break.
"I wasn't that surprised," said Murray. "I mean, stuff like that happens daily in tennis matches, in sport, the stuff that some people say on football pitches and in basketball and all sorts of sports.
"I mean, it was very, very mild in comparison to what happens in other sports. It's just one of those things."
Murray would not reveal exactly what had been said, but added: "People will want to make a big deal of it and it isn't really a big deal. There's no hard feelings."
Federer agreed, saying: "It wasn't a big deal. We just looked at each other one time. That's OK, I think, in a three-and-a-half hour match. We were just checking each other out for bit. I mean, that wasn't a big deal for me. I hope not for him."
And the Swiss, 31, admitted the match had felt like "a chase" as he was constantly trying to keep in touch with Murray.
"I think overall he probably created more chances than I did," said Federer. "I had difficulties getting into his service games time and time again, like I usually do against him.
"I think he started off serving well, and then, fifth set, obviously he did well. I think he played a bit more aggressive because he did create more opportunities over and over again."
