Britain's Andy Murray faces world number two Roger Federer in the US Open final at 2200 BST today. I'm still not sure what sounds stranger: Federer as the world number two or a British player in a Grand Slam final.
For both men, it is a potentially career-defining match. Murray can capture the major title that has eluded British men since Fred Perry lifted the US Open trophy 72 years ago. Federer can make it five in a row in New York, and in doing so prove to his doubters that the king is very far from dead.
"He's probably the greatest player ever. To get a chance to play him in a Grand Slam final is an honour," said Murray after sweeping aside world number one Rafael Nadal in the semi-finals.
Don't be fooled. Murray may be in awe of Federer's achievements, but the Scot is not afraid of big names. Never has been.
He pushed Federer close in Bangkok back in 2005 when Murray was playing his first Tour level final at the age of just 18 and he hasn't lost to the Swiss maestro since, winning their encounters in Cincinnati in 2007 and Dubai earlier this season.
As he has said himself, Murray rarely blows his opponents away (although Stanislas Wawrinka may disagree). He mixes up the pace, he dares to go for the unexpected rather than the obvious, he messes with his opponent's mind.
According to the stats, Nadal made 40 unforced errors in the semi-final, a catastrophic amount for the famously stingy Spaniard, but unforced? Murray, and many of those who were watching, would no doubt disagree. In the final, Federer's forehand - which has been unreliable all season - will be under intense scrutiny.
Nonetheless, John McEnroe probably isn't alone in tipping Federer to beat Murray. This, after all, is the Briton's first major final, and Federer's 17th. The world number two has not experienced defeat at Flushing Meadows since 2003, a run of 33 matches. He has lost one Grand Slam final outside Roland Garros, and won 12. He also looked back to his mind-blowing best in a four-set semi-final win over Novak Djokovic - which included a quite astounding lob-smash, yes lob-smash, from the baseline which has to be seen to be believed (check out a video-sharing website near you).

It is unquestionably a final to be savoured - so who's your money on?
