Seventeen-time Grand Slam winner Roger Federer says he did not expect to reach the Australian Open semi-finals after a six-month injury lay-off, the BBC reported.
The four-time champion in Melbourne is making his competitive return after last playing at Wimbledon in July.
Federer beat Mischa Zverev 6-1 7-5 6-2 to set up Thursday's last-four match against fellow Swiss Stan Wawrinka.
"Feeling as good as I am, playing as good as I am, that's a huge surprise to me," said the 35-year-old.
"If someone would have told me I'd play in the semis against Stan, never would I have called that one.
"For Stan, yes, but not for me. I honestly didn't even know a few days ago that he was in my section of the draw or I'm in his section."
Federer, who has not won a Grand Slam title since triumphing at Wimbledon in 2012, had been sidelined by a knee injury throughout the second half of last year and has slipped from third in the world to 17th.
He played in the non-ranking Hopman Cup in Perth earlier in January, but has come through 18 sets in Melbourne.
"I think winning back-to-back matches in best-of-five sets against quality, great players has surprised me most," he said.
"Really that's been for me the big question mark, if I could do that so early in my comeback.
"I felt I was always going to be dangerous on any given day in a match situation. But obviously as the tournament would progress, maybe I would fade away with energy, you know, that kind of stuff."
Federer holds an 18-3 winning record against Wawrinka, but the 31-year-old will go into the semi-final as the world number four and looking for a second consecutive Grand Slam title after last year's US Open success.
Federer has won their past two meetings, at the ATP World Tour Finals and in the US Open in 2015, but Wawrinka holds a Grand Slam win against his Davis Cup team-mate, coming in the quarter-finals of the French Open in the same year.
"Against Roger, it's always special because he's so good. He's the best player of all time," said the three-time Grand Slam winner.
"He has an answer for everything. But I managed to beat him in a Grand Slam, so we'll see.
"It's great to see him back at that level. Hopefully I can manage to play a great match."
